The magnetic cooling of YTiO3 compound for magnetic refrigeration

Abstract

We theoretically conducted a study on the magnetic behaviors and magneto-caloric performance of the YTiO3 compound, a studied system in this research paper. In accordance with the main objective if this paper, we restricted our research to only studying a number of the system-related elements such as the magnetization M(T), the inverse magnetization M−1 (T), the isothermal magnetic hysteresis loop (M − H), the magnetic entropy change (ΔSM), the relative cooling power (RCP) and the refrigerant capacity (RC). By so doing, we reached a number of results as: the inverse magnetization M−1(T), showed that the Curie temperature (Tc) of the YTiO3 compound was 26.5 K; the largest of the hysteresis loop H(M) at low temperatures indicates that the YTiO3 compound belongs to hard magnetic materials; and at H = 5T, the maximum values of the magneto-caloric effect (MCE), which were represented by the magnetic entropy change (ΔSM), the relative cooling power (RCP), and the refrigerant capacity (RC), were found to be 1.91 J/kg K and 11.45 J/kg and 8.59 J/kg, respectively.
