Abstract

The effect of Co content on magnetocaloric effect (MCE) in CoxZn1−xFe2O4 (CZF) with x = 0, 0.1, 0.2, 0.3, and 0.4, prepared by auto-combustion technique, has been investigated by phenomenological model. The results show that MCE for CZF nanoparticles is enhanced strongly with Co content especially for high Co content samples. In addition, MCE in CZF nanoparticles is tunable with Co content over a large operating temperature range. MCE of CZF nanoparticles are significantly better than MCE of Ni58Fe26Ga28, MnAs films, and Ge0.95Mn0.05. It is recommended that that MCE in CZF nanoparticles is favorable for magnetic refrigeration in a wide temperature range, including room temperature.
