摘要：

Er-166 Mossbauer spectroscopy has been used to study the magnetic ordering of erbium moments in Er3Ge4. We find that the average Er moment is less than 80% of its free-ion value, and we have confirmed that at 1.5 K, the moment associated with Er atoms on the 4c site is 15% smaller than that on the 8f site. The hyperfine field at the 4c site declines much more rapidly with increasing temperature than that at the 8f site, however our data show no indication of the spin re-orientation claimed to occur at similar to4 K.
