- 論文の詳細を見る
NMR study has been made on various antiferromagnetic α-Mn alloys at liquid helium temperatures. The alloys used are α-Mn with V, Cr, Fe, Co, Ni, Ru, re, Al and Zn impurities. The measurements in α-MnFe alloys show that Fe atoms occupy site IV and increase the magnetic moments of Mn atoms at every site. Similar behavior is observed in Co, Ni and Ru alloys. On the other hand, Cr or V atoms prefer either site I or one of site II, decreasing the magnetic moments of surrounding Mn atoms. The changes both of the internal fields of Mn^<55> and of T_N are explained by the occupation of sites by several impurity atoms. The changes of the lattice constant and of the average number of d-electrons have also an important effect to the magnetism of α-Mn alloys.
