FeNiCuMnTiSn x multicomponent alloys ( x = 0, 0.05, 0.1, 0.5, and 1 where x denotes the adding amount in atomic percentage when other elements are taken as 1) are prepared by an arc furnace. The results show that the crystal structure of FeNiCuMnTiSn x alloys transforms from mixed intermetallic compounds to a single crystal structure (zinc blende structure) with the increasing of Sn content. The magnetization of the FeNiCuMnTiSn x alloys gradually increases from 0.34 to 15.8 emu · g −1 with the increasing x , the magnetic transformation undergoes from the paramagnetism ( x = 0, 0.05, 0.1) to superparamagnetism ( x = 0.5) finally to soft magnetism ( x = 1) at room temperature. We use computer simulation and find that the magnetism of alloys appears when Fe atoms replace Ni atoms.
