    Neue Beobachtungen über die Struktur des Zirkulärmuskels im Dünndarm bei Wirbeltieren (1937)

    Notes: Zusammenfassung 1. Eine besondere Teilung des Zirkulärmuskels des Dünndarms in eine innere und eine äußere Schicht wurde aufgewiesen und beschrieben bei verschiedenen Wirbeltieren: Fischen, Amphibien, Reptilien, Vögeln, Säugetieren und beim Menschen. Im Dickdarm findet sich die gleiche Anordnung. 2. Eine rudimentäre innere Schicht des Zirkulärmuskels ist vorhanden in eben geworfenen jungen Hunden, in neugeborenen Kindern und menschliche Feten. Ihre Entwicklung wird in der Entwicklungsperiode nach der Geburt vollendet. 3. Die Besonderheiten dieser Muskelschicht sind beschrieben und durch Mikrophotographien illustriert. 4. Die verschiedene Morphologie dieser Schicht in verschiedenen Tieren kann mithelfen, Därme von verschiedener Herkunft zu identifizieren. 5. Diese Schicht ist wahrscheinlich eine Art Syncytium von neuro-muskulärer Natur, wahrscheinlich der Erreger der segmentären Bewegung des Dünndarms und vergleichbar dem spezialisierten System (Purkinjesystem) des Herzens.

    The apparent Dingle temperature in Zn−Mn, Zn−Cr, and Zn−Fe (1975)
    Springer
    The European physical journal 19 (1975), S. 277-284

    Notes: Abstract The apparent Dingle temperature of the 3rd zone needles in several alloys of Zn−Mn, Zn−Cr and Zn−Fe has been determined from the absolute amplitude of the de Haas-van Alphen effect over the temperature range 1.6 K to 4.2 K and the field range 0 to 9 kG. The results show clearly that potential scatteringnot spin scattering dominates in all three systems. In addition, a “cross-over” behaviour in the de Haas-van Alphen amplitudes results from the scattering of the magnetic moments of the impurity spin.

    Magnetic breakdown in zinc (1973)
    Springer
    Journal of low temperature physics 12 (1973), S. 255-262

    Notes: Abstract The magnetic breakdown field between the second and third zones in zinc has been determined from measurements of the absolute amplitude of the de Haas-van Alphen oscillations of the needles by a torque method. By taking the measurements to lower magnetic field and by calculating the curvature of the needles we are able to determine the value of the breakdown field with much greater certainty than previously. With the external field along thec axis, the breakdown field is found to be 3.5±0.3 kG. As the external field is tipped away from thec axis, the breakdown field is found to vary with angle as though the energy gap between the zones were 6.75(1+2.28 cos ϑ) meV for ϑ from 0 to 80°. The Dingle temperature was found to be isotropic within 0.1 K.

    The influence of scattering on magnetic breakdown (1976)
    Springer
    Journal of low temperature physics 22 (1976), S. 535-556

    Notes: Abstract A study of magnetic breakdown between the third zone needles and second zone monster surfaces in the three zinc alloy systemsZnMn,ZnCr, andZnFe shows that the tunneling probability is strongly reduced by electron scattering and that the breakdown fieldH 0 increases linearly with the Dingle temperatureX with a scaling factor of 0.36 kG/K for all alloys. This phenomenon may be understood if we allow the electrons to be scattered during their tunneling through the forbidden region ofk space. A simple semiclassical calculation of this effect yields an expression for the breakdown probability corrected from the conventional expression toP=exp[−(1/H)(H0+αX)], where α is a constant dependent only on the band structure of the solvent.
