Abstract

A unit standard map for YBa₂Cu₃O_7-x superconductors was constructed and indexed from a series of electron channeling patterns (ECPs). (001) pole figures of YBa₂Cu₃O _7-x tapes and bulk specimens with various values of critical current density (J_c) were drawn by using the map covering [001-1̄1̄0-1̄10] stereographic quadrant and ECPs taken from individual grains of the specimens. It was found that preferred orientation of (001) formed in the tape with a decreasing thickness of the tape, which raised J_c significantly. It is concluded that the ECP technique is very useful for the analysis of orientation distribution in small-sized YBa ₂Cu₃O_7-x specimens such as tapes or thin films.
