Abstract: <正> Effect of Mn substitution for Fe in cubic Laves Zr0.1Tb0.9(Fe1-xMnx)2 and Y0.1Tb0.9(Fe1-xMnx)2 com-pounds is presented.Similar results in both systems are obtained: The structure and the magnetism of TbFe2 areboth influenced slightly by a small amount of Y or Zr substitution for Tb;With increasing x value,the latticeconstant increases monotonously;the Curie temperature decreases linearly;while saturation magnetizationincreases linearly.For the small amount of Mn substitution for Fe in both systems,magnetostriction issignificantly larger than that in the pure iron alloys.The largest magnetostriction of|γ-|γ|=2200×10-6at magnetic field of 2×107/4π A/mis obtained for Y0.1Tb0.9(Fe0.95Mn0.052.
