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（例如超导性和巨大磁化）的电子特性对于基本科学和应用都很重要。我们的目的是通过在高温（1000 C）和压力（5-20​​ GPA）的情况下准备新的或不正确的钙钛矿来发现具有著名特性的新材料 - 钙钛矿是密集的相，因此在这种条件下受到青睐。目标材料包括立方体和分层的CR4+钙钛矿，具有多效性质的新材料以及新的磁库层超导体。请求合成的按下和助行器多安维尔模块。材料将以X射线和中子衍射和电子显微镜为特征，并测量导电，磁性和铁电特性。该项目将受益于与其他英国集团进行测量以及领先的欧洲高压合成实验室（通过欧盟成本网络）的合作。
