| 摘 要： | 非晶态(Fe1-xTMx)1-yBy合金的居里温度与x的相关性可用相干势近似作计算。并归于对三次方程的求解。由此所得交换作用JFe-Fe均呈正值,而JFe-TM及JTM-TM均呈负值。对Fe-Mn-B合金,我们所得结论与Onodera的结论不同。关键词：

| Abstract: | A concentration-dependent Curie temperature for amorphous (Fe1-xTMx)1-yBy alloys is given as a solution of a cubic equation using the coherent-potential approximation; and a conclusion has been reached for the exchange inreraction, that JFe-Fe is positive, JTM-TM and JFe-TM are negative. The present conclusion is different from Onodera's result for Fe-Mn-B alloys. |
