The results are compared with those for LaCrO3, LaFeO3 measured earlier. The PAC probe, 111In → 111Cd, was introduced in the oxide lattice by means of chemical reaction during sample preparation. In the present work, the temperature dependence of the electric quadrupole interaction parameters, for LaCoO3 was investigated. The resulting systematics of EFG at 111Cd, in La(Cr,Fe,Co)O3 perovskites, reveals a linear dependence with temperature.509-513perovskiteslanthanum oxideschromium oxidesiron oxidescobalt oxidesdifferential paccadmium 111magnetismelectric fieldstemperature dependenceTexto completo de eventohttps://orcid.org/0000-0002-2664-5531https://orcid.org/0000-0002-4499-5949
