High-Pressure Synthesis of SrCu3Mn4O12: A Room-Temperature Ferrimagnetic Semiconductor with Spin-Polarized Electronic Structure
A-site-ordered quadruple perovskites (AA′3B4O12) exhibit rich electronic and magnetic behaviors arising from the coexistence of multiple transition-metal sublattices. Here we report the high-pressure synthesis and comprehensive characterization of SrCu3Mn4O12, a previously unknown Sr-based member of the A2+Cu3Mn4O12...
