Effect of Mn substitution for Fe in cubic Laves Zr_(0.1)Tb_(0.9)(Fe_(1-x)Mn_x)_2 and Y_(0.1)Tb_(0.9)(Fe_(1-x)Mn_x)_2 com-pounds is presented.Similar results in both systems are obtained: The structure and the magnetism of TbFe_2 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~(-6)at magnetic field of 2×10~7/4π A/mis obtained for Y_(0.1)Tb_(0.9)(Fe_(0.95)Mn_(0.05)_2.
