    Orbital polarization transition metal oxides (invited) (abstract) : 35th annual conference on magnetism and magnetic materials (1991)

    Notes: One of the most controversial topics in condensed matter physics concerns the nature of the electronic structure of transition metal oxides. Unpolarized band structure calculations predict metallic ground states for these oxides, whereas experimentally they are insulating. This led to the development of the Mott insulator picture for these materials fifty years ago. Later, though, Slater's group showed that by taking into account spin polarization, one could produce insulating gaps from band theory for MnO and NiO. The gaps are too small, the size of the gap actually being determined by the Mott-Hubbard U, but this led to a hope that on symmetry grounds one could also obtain gaps for the other two metal oxides, FeO and CoO. In these two cases, there is an unquenched orbital moment, which might be important for this purpose. Recently, a theory has been developed by Erickson, Brooks, and Johansson for including an orbital polarization correction to local spin density theory.1 The author in turn showed that such a correction can lead to insulating gaps for CoO and FeO.2 A discussion of these results, including the calculated sizes of the moments, as well as related work on insulating mixed valent TmSe, will be presented in this paper.

    Study of low-energy-electron forward focusing effects on highly oriented pyrolytic graphite using scanning auger microscopy (2002)

    Notes: The effects of the electron diffraction in highly oriented pyrolytic graphite are studied in an incident electron beam of energy range 500–700 eV using scanning Auger microscopy. The intensity of the exiting electrons monitored by a cylindrical-mirror analyzer can be well interpreted as the joint effect of incident and exit forward focusing along the close-packed 〈21¯1¯2〉-type atomic chains, with the contribution from forward focusing along the secondary close-packed atomic chains increasing rapidly as the beam energy increases. Incident beam effects contribute greatly to the variation in the intensity of the exiting electrons. Increasing the beam energy in this range also increases the anisotropy observed in the angular distribution of the intensity of both elastically scattered and Auger electrons. © 2002 American Institute of Physics.

    THE RENOVATION OF DOWNLAND PERMANENT PASTURE II. (1957)

    Notes: An experiment, A, involving dates and methods of application of 2,4-D (amine) as a preliminary treatment in the renovation of a poor downland permanent pasture, followed by surface cultivations and sowing of S.24 perennial ryegrass and S.100 white clover, was carried out at Hurley between 1953 and 1955.In spite of initial differences in the establishment of S.24 and S.100, pre-treatment with herbicide had no effect upon the cover of sown and unsown perennial ryegrass and white clover two years later. At this date, perennial ryegrass contributed one-quarter and one-eighth, and white clover one-third and one-quarter, to the total cover of renovated and unrenovated plots respectively.The increase in dry-matter yield resulting from renovation was approximately 10 per cent. This was considered small in relation to the estimated improvement in yield brought about by grazing management and manuring in the course of the trial.In experiment B, plots receiving herbicide were given differential management and manurial treatments after spraying in an attempt to control the ingress of undesirable creeping grasses. The results indicated that this ingress could be checked by close grazing soon after spraying.

    THE RELATIONSHIP BETWEEN COMPETITION AND DEFOLIATION IN PASTURE (1960)

    Notes: Field trials were carried out on a downland permanent pasture at the Grassland Research Institute, Hurley, between 1953 and 1955, to investigate the factors involved in competition in pasture undergoing periodic defoliation. Response to competition was estimated by comparing the yield of species units (either individual plants or close groups of shoots) growing normally in the pasture with the yield of matched units from which the surrounding herbage had been removed. The species studied were cocksfoot, red fescue, creeping bent, plantain, ox-eye daisy and bulbous buttercup. In addition to the estimation of normal competition for environmental resources in pastures of differing height, two special effects upon species due to the presence of surrounding herbage were investigated following unusual results from competition tests in swards under periodic defoliation. First, the influence of surrounding herbage in modifying the growth habit of a species, causing it to grow in a more erect manner, and consequently to suffer more on defoliation at a specific height than in the absence of competition. Secondly, a decreased yield after defoliation, not associated with changes in the growth habit of the species, which was ascribed to an increase in top/root ratio brought about by shading during the preceding period of competitive growth. The effect of selective defoliation of a species in relation to the herbage surrounding it was also studied. Differences in the degree of defoliation of a species and its surrounding herbage had a marked effect upon the degree of competition exerted by the latter upon the former, increasing it when the species was preferentially defoliated and decreasing it when the surrounding herbage was preferentially defoliated. The factors involved in pasture competition under periodic defoliation are listed and discussed.

    THE INFLUENCE OF VARIOUS GRAZING TREATMENTS UPON THE BOTANICAL COMPOSITION OF A DOWNLAND PERMANENT PASTURE (1957)

    Notes: In spring 1952, a trial was laid down at Hurley to compare the botanical effects of five grazing treatments upon a low-fertility downland permanent pasture. The treatments were: dose and lenient rotational cattle grazing, close rotational sheep grazing and continuous grazing by cattle and by sheep. The trial was concluded in autumn 1955.Continuous cattle grazing and close rotational cattle grazing resulted in a sward with a high proportion of forbs. With sheep under the same grazing systems, grasses predominated. An intermediate grass/forb balance was attained under lenient rotational cattle grazing. Legumes contributed more under rotational grazing than under continuous grazing.The grazing treatments most favourable to the major species were: For creeping bent—both sheep grazing treatments; for ribwort plantain—all cattle grazing treatments; for white clover—all rotational grazing treatments; for cocksfoot—lenient rotational cattle grazing; for ox-eye daisy—close rotational cattle grazing; for red fescue—lenient rotational cattle grazing and continuous sheep grazing. Bulbous buttercup and rough-stalked meadow grass showed no significant response to differential grazing treatments.The relative degree of consumption by stock of individual species was estimated by comparing the yields from matched pairs of groups of shoots harvested before and after each grazing spell (rotational treatments) or of areas protected from and exposed to grazing (continuous treatments). A close relationship was established between the intensity of grazing experienced by species and their final status in the swards. Accessibility appeared to be as important as palatability in determining the degree to which individual species were grazed.The resulting swards differed only slightly in agronomic quality. The lack of any clear advantage from rotational grazing was attributed to low levels of plant nutrients, since these probably limited the development of the more valuable grasses and of white clover.

    THE LOCAL INFLUENCE OF CATTLE DUNG AND URINE UPON THE YIELD AND BOTANICAL COMPOSITION OF PERMANENT PASTURE (1958)

    Notes: A study was made of the local effects on yield and botanical composition of the herbage of cattle dung and urine applied to permanent pasture as simulated defaecations and urinations.A single application of urine had a negligible effect upon botanical composition. In the 2-ft.-diameter circle around dung patches there was an increase in cocksfoot, creeping bent, red fescue and white clover, and a decrease in herbs.Urine patches were neglected by grazing stock for short periods only. Herbage around dung patches was neglected for a period varying from 13–18 months. The effect of this neglect was to restrict the spread of white clover around dung patches in comparison with similar plots kept short by cutting.Yield response to urine in the area of deposition lasted for two cuts following application, response to dung for four cuts. An increase in crude-protein content of the herbage was recorded only in samples taken one month after application of dung or urine, and not later.Increases in crude-protein yield following spring applications of dung or urine were greater than those following autumn applications. The inferiority of autumn applications may be attributed to winter leaching of nitrogen.
