摘要：

The normal state of LuNi2B2C, one member of a new family of intermetallic superconductors, has been probed by B-11 NMR. The B-11 nuclear spin-lattice relaxation rate, 1/T1, and the Knight shift have been measured between 20 and 350 K. It was found that 1/T1T is more enhanced at low temperatures than the Knight shift, which has a weak temperature dependence. This result indicates that antiferromagnetic spin fluctuations contribute considerably to 1/T1T at low temperatures in the normal state.
