Аннотация: The features of the characteristics of LnCoO(3) cobaltites, where Ln is a rare-earth element, are discussed. Both experiment and theory demonstrate that their essentials are related to the low-spin ground state of cobalt ions. The thermally induced occupation of the excited high-spin state gives rise to peaks in the magnetic suscepПоказать полностьюtibility, specific heat, and thermal expansion, as well as to a smooth insulator-metal transition. The analysis is based both on the data from the current literature concerning LaCoO3 and in many aspects on our own studies of GdCoO3 and La1-x Gd (x) CoO3 solid solutions.
