The structure, magnetization and magnetostriction of Sm(Zn1-xTx) (T=Fe, Co) polycrystalline alloys were investigated by X-ray diffraction, vibrating sample magnetometer and standard strain gauge techniques. It is found that annealed SmZn1-xFex alloys show a single Sm(Zn,Fe) phase with the CsCl-type cubic structure when x≤0.2. SmZn1-xCox alloys are a single Sm(Zn,Co) phase when x≤0.15 and the Sm-rich phase appears when x>0.15. The Curie temperature for SmZn1-xFex alloys increases with increasing Fe content in the range of 0≤x≤0.2 and that of SmZn1-xCox alloys slowly does in the same composition range. When Fe is substituted for Zn in SmZn compound, the magnetization and magnetostriction increase with increasing the Fe content when x≤0.2 and when x≤0.1, respectively. The magnetostriction of Sm(Zn1-xCox) alloys increases with increasing the Co content under the magnetic field of 320 kA/m in the range of 0< x≤0.1.
