Magnetocaloric Properties and Critical Behaviour of the Sm2Ni17 Compound

This paper presents a detailed study in the critical region around Curie temperature to determine universality class of Sm2Ni17 intermetallic compound. The magnetocaloric effect has been studied on basis experimental measurements magnetization. Maxwell’s relation and phenomenological model are employed find change magnetic entropy. compound variation entropy with moderate maximum wide range operating temperatures. Numerous approaches have used explore spontaneous magnetization behaviour inverse susceptibility, including modified Arrott technique, Kouvel–Fisher approach, fitting isotherm. scaling hypothesis confirm validity interdependence exponents associated these phenomena.
