Influences of La and Ce doping on giant magnetocaloric effect of EuTiO |
(color online) (a) Temperature dependence of ZFC and FC magnetizations of the EuTiO3 and Eu0.9R0.1TiO3 (R = La, Ce) under a magnetic field of 0.1 kOe; (b) the temperature dependence of inverse susceptibility fitting to the Curie–Weiss law. |
