| 摘 要： | 本文研究了利用气相急冷方法获得的非平衡bcc和fccFe1-xPdx合金在室温和4.2K下的穆斯堡尔谱,用拟谱方法获得了超精细相互作用参量及超精细场分布P(H),在bccFe1-xPdx合金中,超精细场随x增加而稍有增加,而在fcc相合金中,超精细场随x增加而减少,用半经验公式分析了Fe-Pd合金中超精细场和磁矩之间的相互关系。关键词：

| Abstract: | M?ssbauer spectra were taken at 4.2 K and 290 K for the bcc and fee Fe1-xPdx alloys produced by vapor quenching. The hyperfine interaction parameters and hyperfine field distribution curves were obtained with spectrum fitting method. With increasing x, the average hyperfine field, Hhf increases in bcc Fe1-xPdx alloys, while Hhf decreases in fee alloys. The concentration dependence of Hhf can be explained by using a semi-empirical formula.
