Abstract

In order to study the reentrant behavior in HoNi₂B₂C compound, the variation of the superconducting transition temperature T_c against the Nd substitution concentration x in polycrystalline samples of Ho_1-xNd_xNi₂B₂C was systematically investigated by the measurements of electrical resistivity in the temperature range from 2 K to 20 K. The Nd substitution for Ho showed the similar effect to break Cooper-pairs as an applied magnetic field. The pair breaking near T_m, which indicates the incommensurate magnetic ordering temperature of HoNi₂B₂C compound, is strong enough to suppress superconductivity, resulting in two distinct superconducting regions above and below T_m in the T-x phase diagram. The variation of T_c against Nd concentration x showed the breakdown of de Gennes scaling.
