on the magnetic properties of high entropy intermetallic compounds

High entropy intermetallic compounds (heics) are an interesting class of materials combining the properties of multicomponent solid solutions and the ordered superlattices in a single material. in this work, microstructural and magnetic properties of (cocufemnni)al, (cocufemnni)zn3, (fecomnnicr)3sn2, (feconimn)3sn2 and cu3(insnsbgage) heics fabricated by induction melting are studied. the magnetic properties of the heics was determined mainly by the nature of the magnetic momentum of the constituent elements. (cocufemnni)al and (cocufemnni)zn3 displayed ferromagnetic behavior at 5 k, while indicated linear dependency of magnetization vs. magnetic (i.e. paramagnetic or antiferromagnetic state) at 300 k. the magnetization of (fecomnnicr)3sn2, (feconimn)3sn2 and cu3(insnsbgage) heics at 300 k exhibited a nearly linear dependency to magnetic field. among all the investigated samples, (cocufemnni)al exhibited the best magnetic properties with a saturation magnetization of about ms = 6.5 emu/g and a coercivity of about hc = 100 oe.
