Abstract

Electrical resistivity of single-crystal HoMo₆S₈ has been measured at low temperatures down to 0.01 K. By slow cooling, the resistivity in the re-entrant normal state below T_c2 is recovered up to 98 % of its value above T_c1. This suggests that there still remains a little superconductive region not due to Bloch walls, but rather to ferromagnetic magnetic microdomains of comparatively small sizes. By rapid cooling, on the other hand, the superconductivity above T_c2 has been found to be quenched at low temperatures below T_c2. This quenched superconductivity, coexisting with the quenched modulated magnetic structure, is destroyed as a function of time and magnetic field, which seems attributed to the growth of the microdomains.
