Electronic properties of metal oxides such as superconductivity and colossal magnetoresistance are important both for fundamental science and for applications. We aim to discover new materials with notable properties by preparing new or ill-characterised perovskites at high temperatures (1000 C) and pressures (5-20 GPa) - perovskites are dense phases and so are favoured under such conditions. Target materials include cubic and layered Cr4+ perovskites, new Bi materials with multiferroic properties, and new magnetic cuprate superconductors. A press and a Walker multianvil module are requested for synthesis. The materials will be characterised by X-ray and neutron diffraction and electron microscopy, and conducting, magnetic and ferroelectric properties will be measured. The project will benefit from collaborations with other UK groups for measurements and with leading European high pressure synthesis laboratories (through an EU COST network).

金属氧化物的超导电性和巨磁电阻等电子性质对基础科学和应用都具有重要意义。我们的目标是通过在高温（1000 ℃）和高压（5-20 GPa）下制备新的或特征不佳的钙钛矿来发现具有显著性能的新材料-钙钛矿是致密相，因此在这种条件下是有利的。目标材料包括立方和层状Cr 4+钙钛矿，具有多铁性的新Bi材料和新的磁性铜酸盐超导体。合成需要一台压机和一个步行者多砧模块。这些材料将通过X射线和中子衍射以及电子显微镜进行表征，并将测量导电，磁性和铁电特性。该项目将受益于与其他英国测量团体和欧洲领先的高压合成实验室（通过欧盟COST网络）的合作。
