Abstract

The effects of Ni substitution on the magnetic properties and magnetocaloric effect (MCE) of (Mn1-x Nix) 3 Sn2 compounds (x=0-0.5) have been investigated by x-ray diffraction and magnetization measurements. It was found that Ni substitution decreases the crystal cell volume and the magnetic transition temperatures compared with pure Mn3 Sn2. The MCE for all samples has been calculated from the magnetization data in terms of the isothermal magnetic entropy change Î” SM. The maximum values of Î” SM max at the magnetic phase transition temperatures resulting from a change in magnetic field of Î”H=5 T were found to be 28.2 mJ/ cm3 K for Mn3 Sn2 (TC1 âˆ¼257 K), increasing to 31.2 mJ/ cm3 K for (Mn0.9 Ni0.1) 3 Sn2 (TC âˆ¼167 K).
