摘 要：The phases and magnetocaloric effect in the alloys （Gd1-xErx）5Si1.8Ge2.2 with x=0, 0.1, 0.2 and 0.3 were investigated by X-ray diffraction analysis and magnetization measurement. The samples were single phase with the monoclinic Gd5Si2Ge2-type structure. With the increase of Er content, the Curie temperature （Tc） decreased obviously from 253 K of the alloy with x=0 to 114 K with x=0.3. The maximum magnetic entropy changed in the samples of （Gd1-xErx）5Si1.8Ge2.2 with x=0.0, 0.1, 0.2 and 0.3 were 6.88, 8.32, 9.59 and 10.24 J·kg-1·K-1 respectively in the applied field change of 0～2.0 T.
