dc.description.abstractWe report the magnetic entropy change (ΔSm) in magnetoelectric Eu1-xBaxTiO3 for 0.1 ≤ x ≤ 0.9. We find -ΔSm = 11 (40) J/kg·K in x = 0.1 for a field change of 1 (5) T, respectively, which is the largest value among all Eu-based oxides. ΔSm arises from the field-induced suppression of the spin entropy of Eu2+:4f7 localized moments. While |-ΔSm| decreases with increasing x, |-ΔSm| = 6.58 J/kg·K observed in the high spin diluted composition x = 0.9 is larger than that in many manganites. Our results indicate that these magnetoelectrics are potential candidates for cryogenic magnetic refrigeration. © 2014 AIP Publishing LLC.
