Phase diagram and isotope effect in (PrEu)_0.7Ca_0.3CoO_3 cobaltites exhibiting spin-state transitions

A. V. Kalinov, O. Yu. Gorbenko, A. N. Taldenkov +11

We present the study of magnetization, thermal expansion, specific heat, resistivity, and a.c. susceptibility of (Pr $_{1 - y}$ Eu $_{y}$ ) $_{0.7}$ Ca $_{0.3}$ CoO $_{3}$ cobaltites. The measure…
