M?SSBAUER EFFECT OF VAPOR QUENCHED Fe-Pd ALLOYS
气相急冷Fe-Pd合金的穆斯堡尔谱研究

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.
