Large-sized and highly-uniform superconducting RE123 single crystals by top-seeded solution-growth: A platform for physical research
The last two decades have seen a growing trend towards sizable single crystals of REBa2Cu3O7−δ (RE123, RE = rare earth elements) with fine quality, which have been attracting considerable interest in the study of superconductivity. As an advanced and classic method, top-seeded solution-growth (TSSG) is the only technique to date for producing RE123 single crystals with dimensions of 2 cm, e.g., a Y123 single crystal of 19.8 × 19.5 mm2 in a-b plane and 16.5 mm in height. Recently, novel approaches were developed such as crystal-pulling combined with continual cooling for rapid growth to attain a large-sized RE123 crystal, and the utilization of dopant-added crucibles for continuous growth to produce highly-uniform doped-Y123 crystals. Consequently, researchers from several tens of physical laboratories worldwide have been benefiting from TSSG-produced RE123 single crystals and generating excellent collaborative work. This paper provides an overview of the progress and achievements on the growth of superior RE123 single crystals by TSSG for fundamental studies and practical applications, focusing on three aspects including crystal enlargement, RE123 stoichiometry control and cation doping. The mechanism of crystal growth and the correlation between phase formation and superconducting properties are comprehensively elucidated on the basis of distinctive features of phase diagrams of RE–Ba–Cu–O systems.
期刊介绍:
Progress in Solid State Chemistry offers critical reviews and specialized articles written by leading experts in the field, providing a comprehensive view of solid-state chemistry. It addresses the challenge of dispersed literature by offering up-to-date assessments of research progress and recent developments. Emphasis is placed on the relationship between physical properties and structural chemistry, particularly imperfections like vacancies and dislocations. The reviews published in Progress in Solid State Chemistry emphasize critical evaluation of the field, along with indications of current problems and future directions. Papers are not intended to be bibliographic in nature but rather to inform a broad range of readers in an inherently multidisciplinary field by providing expert treatises oriented both towards specialists in different areas of the solid state and towards nonspecialists. The authorship is international, and the subject matter will be of interest to chemists, materials scientists, physicists, metallurgists, crystallographers, ceramists, and engineers interested in the solid state.
