- 論文の詳細を見る
Amorphous alloys having the composition (Fe_<1-x>Mn_x)_<80>B_<20> (0≤x≤0.25) have been studied by Mossbauer spectroscopy and magnetization measurements. All the samples show ferromagnetic behaviors. The saturation magnetization at 0 K, the Curie temperature T_C and the average hyperfine field decrease monotonically from 197 emu/g, 680 K and 286 kOe in x=0 to 107 emu/g, 383 K and 178 kOe in x=0.25. The concentration dependence of T_C gives a conclusion for the exchange interaction that J_<Fe-Mn> and J_<Mn-Mn> are relatively small positive and negative values, respectively, compared with J_<Fe-Fe>. The magnetic moments of the Fe and Mn atoms are discussed in connection with the exchange interaction.
