    Notes: Resistivity measurements have been made on EuMo6S8 and EuMo5WS8 single crystals in the temperature range 1.5–300 K under pressures between ambient and 20 kbar. In contrast to the recently reported results on sintered or melted material, the resistivity has a metallic behavior. No semiconductor behavior is observed in either type single crystal. The strong scattering effects lead to an electronic mean free path equal to the interatomic Mo-Mo distance. The possibility of spin fluctuations associated with the molybdenum atoms is discussed. The superconductivity appears in either type crystal at about the same pressure (10 kbar).

    Superconductivity associated with ferromagnetic domain walls in HoMo6S8 and (Er1−xSnx)Er4Rh6Sn18 (1985)

    Notes: The compounds HoMo6S8 and (Er1−xSnx)Er4Rh6Sn18 (respectively, Ho-Mo-S and Er-Rh-Sn in the following) are known to be reentrant superconductors, the superconductivity being destroyed by the onset of long-range ferromagnetic order at low temperature. For the first time, the percolation of domain "walls'' superconductivity has been produced below 0.2 K in Ho-Mo-S single crystals, confirming a systematic study of sintered samples and theoretical expectations. In addition, the ac susceptibility of Er-Rh-Sn single crystals, measured below 0.5 K, is large and positive for large ac fields and nearly equal to −1/4π for low ac fields. This fact confirms the existence of superconducting domain "walls'' which screen the ac field.

    Itinerant ferromagnetism and superconductivity in bct ErRh4B4 (1985)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The body centered tetragonal ErRh4B4 compound undergoes an itinerant ferromagnetic transition at Tm=21 K characterized by a susceptibility equal to the inverse of the demagnetizing coefficient. The itinerant ferromagnetism does not prevent the simultaneous presence of the superconductivity from 7.7 K down to 0 K. The diamagnetic ac susceptibility can be calculated from the ferromagnetic one. The coexistence of itinerant ferromagnetism and superconductivity among d electrons would be one of the most convincing arguments in favor of "odd-parity'' superconductivity.

    Introduction of bismuth into the highT c superconductor La2−x Sr x CuO4−y (1987)

    Notes: Abstract Novel high-T c superconductors La2−x Bi x′ Sr x−x′ CuO4−y have been isolated and studied. The influence of the experimental conditions of synthesis on the superconductivity has been especially studied for the composition La1.7Bi0.1Sr0.2CuO4−y ; it is shown thatT c decreases as oxygen is introduced into the matrix, likely due to the partial oxidation of Bi(III) to Bi(V). The highT c value observed for one sample (T c ≃42 K), as compared withT c ≃38 K of La1.8Sr0.2CuO4−y suggests that bismuth is also a potential candidate for improving the superconducting properties in these oxides.

    Magnetic field-induced superconductivity in the ferromagnetic state of HoMo6S8 (1987)
    Springer

    Notes: Abstract The Chevrel-phase HoMo6S8 is one of the few known ferromagnetic reentrant superconductors, having an upper superconductive critical temperatureT c1 =1.78 K, a Curie temperatureT m =0.75 K, and reentering into a normal ferromagnetic state belowT c2 =0.64 K. After a brief survey of the characteristic properties of HoMo6S8, we present new results obtained by simultaneous resistance and magnetization measurements on a single crystal of HoMo6S8, performed in the whole temperature range 35mK≤T≤4.2 K and for several orientations of the easy magnetization axis with respect to the applied magnetic field. Magnetic field-induced superconductive transitions are observed well belowT c2 in the ferromagnetic state. Those transitions can be understood as the first experimental observation of a purely electromagnetic effect earlier suggested by Ginzburg: if the internal field is antiparallel to the spontaneous magnetization, the magnetic induction may be reduced below its critical value and a superconductive transition may take place. It is possible if exchange interactions are negligible; our results concerning the anisotropy of the internal upper critical fieldH c2 are consistent with that requirement. We also discuss the possible origins for the low-resistance state in zero field: it might be due to domain wall superconductivity.
