Abstract:

The cobalt deficient double perovskites EuBaCo2-xO6-delta with x = 0-0.1 were obtained both as powders and as single crystal. Formation of cobalt vacancies in their crystal lattice was shown to be accompanied by the formation of oxygen ones. Chemical lattice strain caused by this cooperative disordering of cobalt and oxygen sublattices was found to be isotropic contrary to that caused by the formation of oxygen vacancies only. Cobalt deficiency was also shown to lead to lowering overall conductivity and Seebeck coefficient of EuBaCo2-xO6-delta double perovskites as a result of simultaneous decrease of charge carriers' concentration and their mobility as well as number of sites available for electrons and holes transfer. Strong anisotropy of the overall conductivity of the single crystal double perovskites EuBaCo2-xO6-delta was found and explained on the basis of preferential location of oxygen vacancies in the rare-earth- oxygen-(REO-) planes.
