中文摘要	Magnetic properties and magnetocaloric effects (MCEs) of the intermetallic Gd1-xHoxNiIn (x=0-1) compounds have been evaluated by magnetization and heat capacity measurements. The Curie temperature T-C can be tuned from near 100 K to 20 K by substituting Ho for Gd atoms. In addition, all the compounds with Ho atoms undergo two successive magnetic transitions with the decrease of temperature: a paramagnetic (PM) to ferromagnetic (FM) transition around T-C and a spin-reorientation (SR) transition around 7-9K. It is found that both transitions contribute to the magnetic entropy change (Delta S-M). For a field change of 5 T, the maximum values of -Delta S-M for Gd0.4Ho0.6NiIn are 6 J/kg K at T-t=9 K and 10 J/kg K at T-C=52 K, respectively. These two -Delta S-M peaks overlap partly and result in a wide working temperature range of MCE, and thus leading to the largest RC value of 443 J/kg in the Gcli_xHoxNiln system.
