Abstract

Specific heat and magnetization measurements demonstrate that the antiferromagnetic (AFM) phase transition at T N = 5.7 K of EuTiO 3 is rapidly suppressed with Sr doping in Eu x Sr 1−x TiO 3 . Close to x = 0.25, T N = 0 K and AFM order vanishes. Above this critical concentration a finite transition temperature to an AFM phase is observed. The exchange couplings are derived as a function of x and the corresponding low temperature phase diagram is presented. Copyright EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg 2013
