Abstract

High field (up to 5 T) magnetization measurements were performed on both bulk and field-aligned powder samples of RNi₂B₂C (R=Dy, Ho) magnetic superconductors. For T_c=3.8 K, a DyNi₂B₂C superconductor with antiferromagnetic Néel temperature T_N of 10-11 K, and anomalous field-induced weak-ferromagnetic transitions were observed above the superconducting upper critical field H_c2(2 K) of 1.75 kG. The aligned powders show distinct hysteresis characteristics for both fields applied parallel and perpendicular to the tetragonal basal plane. For T_c=7.8 K, HoNi₂B₂C has an incommensurate magnetic ordering temperature T_m of 6 K and T_N of 5.2 K. Anomalous field-induced weak-ferromagnetic transitions were also observed below T_N. No hysteresis can be detected for T_N<T<T_m.
