Abstract :
The structure, magnetization, and magnetostriction of R(Zn1-x Fex)(R=Tb, Dy) polycrystalline alloys were investigated by X-ray diffraction, vibrating sample magnetometry, and standard strain gauge techniques. It was found that TbZn1-xFex consists of a single Tb(Zn,Fe) phase with the cubic CsCl-type structure when x les 0.2. DyZn1-xFex was found to consist of nearly a single Dy(Zn,Fe) phase in the range 0 les x les 0.15. A second Dy-rich phase appears when x > 0.15. The Curie temperature of the RZn1-xFex alloys increases with increasing Fe content when x les 0.2. When Fe is substituted for Zn in RZn compounds, the magnetization increases with increasing Fe content. The magnetostriction of Tb(Zn1-xFex) alloys increases with increasing Fe content when x les 0.1, and that of Dy(Zn1-x Fex) alloys increases in the composition range 0 les x les 0.05
