Abstract
In this study, a new Fe30.7Ni25.7Ga14.6Mn19Si10 without rare earth element high entropy alloy's (HEA) magnetocaloric properties was investigated. The HEA was formed by the suction-casting method. x-ray diffraction (XRD) method was performed for structural analysis. XRD analysis 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 K and 462 K for the as-quenched and annealed alloy, respectively. The Fe30.7Ni25.7Ga14.6Mn19Si10 HEA shows 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.
