非晶态Fe_(90-x)Si_xZr_(10)(x=0,4,7,10)合金是用单辊急冷方法制备的,用提拉样品磁强计测量了样品的磁化曲线和热磁曲线。发现每个磁性原子的平均磁矩μ和Curie温度T_c随Si含量的增加而增加,与相应的非晶态FeSiB合金相比,非晶态FeSiZr合金的μ和T_c明显偏低,认为这一反常现象是Fe-Fe原子间的反铁磁耦合的存在所致。低温下样品的磁化强度与温度的关系较好地符合Bloch T~(3/2)定律,得到自旋波劲度系数D从x=0时的0.37meV·um~2增加到x=10时的0.538meV·um~2,计算出交换相互作用范围都是在最近邻原子间的距离。 The amorphous Fe 90-x Si x Zr 10 (x = 0, 4, 7, 10) alloy was prepared by a single roll rapid quenching method. The magnetization curve and thermal magnetic curve. It is found that the average magnetic moment μ and the Curie temperature T_c of each magnetic atom increase with the increase of Si content. Compared with the corresponding amorphous FeSiB alloy, the μ and T_c of the amorphous FeSiZr alloy are obviously low, which is considered as abnormal The phenomenon is due to the existence of anti-ferromagnetic coupling between Fe-Fe atoms. The relationship between magnetization and temperature at low temperature is in good agreement with the Bloch T ~ (3/2) law, and the spin-wave stiffness coefficient D increases from 0.37meV · um ~ 2 at x = 0 to x = 10 Of the 0.538meV · um ~ 2, calculated exchange interaction range is the distance between the nearest neighbor atoms.
