Abstract
The spin echo NMR of 59 Co in the (Y 1- x Gd x )Co 2 system was observed in both magnetically ordered and paramagnetic states. In YCo 2 , the Knight shift of 59 Co was found to be linear in susceptibility, leading to a hyperfine coupling constant of -89 kOe/ µ B . The zero-field center frequency in the ordered state and both the Knight shift and the relative integrated intensity in the paramagnetic state were observed for over all the concentration. The field dependence of integrated intensity and temperature dependence of Knight shift were also measured in the vicinity of the critical concentration. The results indicate the coexistence of two types of Co atoms in the whole concentration range; one has a magnetic moment which couples antiparallel with the Gd moment and the other has no moment.
