Ground-state properties of the mixed-valence cobaltites Nd0.7Sr0.3CoO3, Nd0.7Ca0.3.CoO3 and Pr0.7.Ca0.3CoO3.
Original language description
Electric, magnetic, and thermal properties of three perovskite cobaltites with the same 30% hole doping and ferromagnetic ground state investigated. With decreasing size of large cations, the FM Curie temperature and spontaneous moments of cobalt are gradually suppressed: TC = 130 K, 55 K and 25 K and m = 0.68 ?B, 0.34 ?B and 0.23 ?B for Nd0.7Sr0.3.CoO3, Pr0.7.Ca0.3.CoO3 and Nd0.7.Ca0.3.CoO3. The moment reduction with respect to the moment of the conventional FM La0.7.Sr0.3.CoO3 (TC = 230 K, m = 1.71 ?B) in the so-called low spin/intermediate spin (IS/LS) state for Co3+/Co4+ was originally interpreted using a phase-separation scenario
