All rights reserved.In this study, a new Fe30.7Ni25.7Ga14.6Mn19Si10 without rare earth element high entropy alloy's (HEA) magnetocaloric properties was investigated. TheHEAwas formed by the suction-casting method. x-ray diffraction (XRD) method was performed for structural analysis.XRDanalysis show that both the as-quenched and annealed alloy have a single body centred cubic(bcc) structure. The result obtained from the Arrott plots indicates that the alloys have the second order magnetic phase transition. The transition temperature from paramagnetic to ferromagnetic transition was observed at 442 Kand 462 Kfor the as-quenched and annealed alloy, respectively. The Fe30.7Ni25.7Ga14.6Mn19Si10 HEAshows magnetic entropy change such as 0.75 Jkg-1 K-1 for as-quenched alloy, 0.90 Jkg-1 K-1 for annealed alloy at 2 T magnetic field.
