摘要：

Magnetic properties of Pm as an impurity in NdNi single crystal were investigated by means of low-temperature nuclear orientation of the Pm-144 isotope. The angular distribution of gamma-ray anisotropy revealed that the direction of the hyperfine field experienced by the nuclei was in the (a, c) plane and made an angle of 29(10)degrees and/or 209(10)degrees with the a axis. The strength of the field was deduced to be 395(48) T with a full-field site fraction of 76(3)% from the temperature dependence of the anisotropy. The beta decay of Pm-144 was found to proceed mainly via the Delta J(beta) = 1 matrix element. A brief discussion of crystal electric field effects and exchange interactions is given.
