Abstract

The paramagnetic susceptibility of YNi₂B₂C single crystal in a high magnetic field is found to be about 2 × 10^-5 cm³/mol, which is one order of magnitude smaller than the previous reports. The paramagnetic behavior is caused by the sample impurity, not by the intrinsic magnetism of the YNi₂B₂C superconductor and shows simple Curie-Weiss behavior. In this case, an upper critical field of the YNi₂B₂C can be easily obtained by extracting the paramagnetic contribution. The upper critical field shows an anomalous behavior, the steep rising at the low temperature region.
