Room temperature magnetocaloric effect of Ce0.65Mg0.35Co3

Abstract

The magnetocaloric (MC) effect of Ce0.65Mg0.35Co3 alloy is simulated using a phenomenological model (PM). MC parameters of Ce0.65Mg0.35Co3 alloy are obtained from modelling findings as the result of simulation for magnetization vs. temperature in a 0.1 T magnetic field. The full-width at half-maximum of 104 K is impressive, providing an important basis for operating the Ce0.65Mg0.35Co3 alloy in the magnetic refrigerator (MR). Since the Ce0.65Mg0.35Co3 alloy may be used as an effective MC material for MR throughout a wide temperature range, it can cover a significant and crucial range of temperatures, including room temperature and lower temperatures. The MC parameters of Ce0.65Mg0.35Co3 alloy are larger than those of metal oxide nanoparticles, ferrites, intermetallic compounds, and manganites that have been published previously, concluding that Ce0.65Mg0.35Co3 alloy can serve as an advantageous MC magnet for the MR.
