Abstract

A comparative study of the structure-sensitive magnetic properties of fine-crystalline YBa2Cu3O y samples obtained by different methods (the sol-gel technique and mechanical activation) is performed. It is shown that a peculiar type of structural disordering extrinsical of macrocrystalline samples of the same compound, is a general property of fine-crystalline samples. This is due to the stabilization of the quasi-equilibrium state with incomplete atomic ordering when synthesizing this compound with a fine-crystalline microstructure.
