Specific heat and magnetization measurements demonstrate that the antiferromagnetic (AFM) phase transition at TN = 5.7 K of EuTiO3 is rapidly suppressed with Sr doping in EuxSr1−xTiO3. Close to x = 0.25, TN = 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.
