摘要：
Detailed measurements of resistivity rho(ab) as a function of temperature and magnetic field have been carried out on DyNi2B2C single crystals. For H parallel to[100], an anomalously large hysteresis effect of superconductivity and a reentrant behavior were observed in the low temperature range (T<2 K). This hysteresis effect is anisotropic in the a-b plane with a maximum value for H parallel to[100], and almost zero for H parallel to[110]. The reentrant behavior and the large hysteresis of superconductivity indicate a strong interplay between magnetism and superconductivity in DyNi2B2C.
