摘      要：A nanocrystalline CoCrFeNiMn high-entropy alloy(nc-HEA)with nano-multiphase structure was prepared by inert gas condensation(IGC)using a laser evaporation ***,the laser-IGC nc-HEA exhibits unexpected ferromagnetic behavior and the Curie temperature(T_(c))increased nearly 10 times compared to any CoCrFeNiMn HEAs prepared by various other *** addition,the saturation magnetization(M_s)and T_(c)of the laser-IGC nc-HEA can be controlled via heat treatment,which is resulting from the formation and structural evolution of magnetic nanophases during *** work widens the design toolbox for high-performance nc-HEAs based upon laser-IGC technique.
