| 中文摘要 | The effects of tin substitution on the phase formation, the Curie temperature, and the magnetic entropy change of the monoclinic Gd5Si1.95Ge2.05 alloy have been investigated. Five Sn-doped Gd5Si1.95-xGe2.05-xSn2x samples were prepared with 2x=0, 0.01, 0.03, 0.05, and 0.10, respectively. Experimental results show that a small amount of Sn doping in Gd5Si1.95Ge2.05 retains the first order structural/magnetic transition, significantly enhances its magnetocaloric effects as well as increase its Curie temperature T-c, but leads to increase in hysteresis loss due to its field-induced monoclinic to orthorhombic phase transformation. The maximum magnetic entropy change of the Sn-doped Gd5Si1.935Ge2.035Sn0.03 sample for the 0-2.0 T magnetic field change reaches 28.9 J kg(-1) K-1 at 277 K, which is twice as large as that of pure Gd5Si1.95Ge2.05 (14.1 J kg(-1) K-1 at 260 K) for the same magnetic field change.
