Recent Progress in Search for New Functional Oxides by High-Pressure Synthesis

Abstract

High-pressure synthesis is a powerful technique in searching for new materials. We have found a large number of functional oxides using this technique. In this article, three topics will be reviewed from our recent works. These are search for magnetic ferroelectrics in Bi, Pb-3d transition metal perovskites, single crystal growth of oxychloride superconductor, Ca_2-xNa_xCuO₂Cl₂, and pressure-induced structural transition in spin ladder compound, SrCu₂O₃.
