Abstract

The ac susceptibility and electrical resistivity of single-crystal HoMo6S8 have been measured to study the metastable superconductivity quenched by rapid cooling down to a low temperature below Tc2. Time development of the ac susceptibility from the quenched superconducting state to the normal ferromagnetic state is explained by the nucleation and growth model at first-order phase transitions. Its relaxation time is approximately proportional to T-6.7 exp(-H/H0) in low magnetic fields at low temperatures. The quenched superconductivity is also destroyed anisotropically by magnetic field. Hysteresis in the resistivity in the magnetic field sweep and magnetic-field-induced zero-resistance state are discussed, considering dynamics of ferromagnetic domains.
