摘要：

The orthorhombic intermetallic compounds DyCu2 and ErCu2 were measured with Dy-161 and Er-166 Mossbauer spectroscopy, respectively. DyCu2, which has a weak magnetic anisotropy parallel to the a-axis, shows no relaxation traject above T(N). In contrast, ErCu2 has a strong magnetic anisotropy parallel to the b-axis and shows a long relaxation traject above T(N) = 11.5 up to 45 K. A very good correspondence is found between the results of ErCu2 obtained by inelastic neutron scattering and by Er-166 Mossbauer spectroscopy.
