The effect of cold deformation on the structure, texture and properties of yttrium high temperature superconducting powders and strips
Autor: V. F. Choporov, E. A. Myasnikova, A. F. Pimenov, V. F. Shamrai, A. A. Babareko, Yu.V. Efimov, T. M. Frolova, A. M. Postnikov, F. R. Karelin
Publikováno v: Journal of the Less Common Metals. 175:29-36
Cold deformation of YBa2Cu3O7 − x (phase 123, Tc = 88.5–92 K) powders and strips causes partial decomposition of the 123 phase, a reduction in the degree of orthorhombicity of the structure up to almost complete degradation, and a decrease in Tc.

Texture of Y- and Bi-HTSC and Methods for its Determination
Autor: A. A. Babareko, V. F. Shamray, Yu.V. Efimov, T. M. Frolova, E. A. Myasnikova
Publikováno v: Crystal Research and Technology. 26:623-630
Investigation of the texture of Y- and Bi-HTSC materials by X-ray techniques involves certain difficulties owing to the peculiarities of their crystal structure which causes the arrangement of reflexes in dense groups and practically precludes the fo
