用转矩磁强计法研究了轻RFe_2(R为La,Ce,Pr,Nd,Sm)溅射非晶膜的磁化强度和温度的关系,通过Ms-T关系确定居里温度,讨论稀土元素对轻RFe_2非晶合金居里温度的影响。在轻RFe_2非晶合金中Fe-Fe原子间的交换作用不为零,而是对总的交换相互作用起主要贡献,轻RFe_2非晶合金的居里温度在室温之上,不同于重稀土非晶RFe_2合金,轻RFe_2非晶合金的居里温度与稀土元素的原子半径和有效自旋不成简单的函数关系,其中LaFe_2和NdFe_2的异常,我们用Nd亚晶格磁矩的分散和La有较大的原子半径尺寸来解释。
The relationship between the magnetization and the temperature of amorphous RFe_2 (R, La, Ce, Pr, Nd, Sm) sputtered amorphous films was studied by using the Torque Magnetometer. The Curie temperature was determined by the Ms-T relationship. The effects of rare earth elements Effect on the Curie Temperature of Light RFe_2 Amorphous Alloy. The exchange between Fe-Fe atoms is not zero in light RFe2 amorphous alloys, but rather contributes to the total exchange interaction. The Curie temperature of light-weight RFe2 amorphous alloys is above room temperature, which is different from that of heavy rare earth The Curie temperature of the amorphous RFe_2 alloy and the light RFe_2 amorphous alloy is not a simple functional relationship with the atomic radius and effective spin of the rare earth elements. The anomaly of LaFe_2 and NdFe_2, Large atomic radius size to explain.
