Abstract

Giant reversible magnetocaloric effects and magnetic properties in Eu0.9R0.1TiO3 (R = La, Ce) are investigated. The antiferromagnetic ordering of pure EuTiO3 can significantly change to be ferromagnetic as substitution of La (x = 0.1) and Ce (x = 0.1) ions for Eu2+ ions. The values of -ΔSM and RC are evaluated to be 10.8 J/(kg·K) and 51.8 J/kg for Eu0.9Ce0.1TiO3 and 11 J/(kg·K) and 39.3 J/kg for Eu0.9La0.1TiO3 at a magnetic field change of 10 kOe, respectively. The large low-field enhancements of -DSM and RC can be attributed to magnetic phase transition. The giant reversible MCE and large RC suggest that Eu0.9R0.1TiO3 (R = La, Ce) compounds could be promising materials in low temperature and low magnetic field refrigerants.
