摘要
Effect of Mn substitution for Fe in cubic Laves ZrTb(FeMn)and YTb(FeMn)com-pounds is presented.Similar results in both systems are obtained: The structure and the magnetism of TbFeareboth 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=2200×10at magnetic field of 2×10~7/4π A/mis obtained for YTb(FeMn.
