报告摘要： Establishing structure-property relationships is often the key to the rational design of new functional materials. The 4d metal oxides are gaining considerable attention in the search for materials with novel properties as a consequence of their tendency to exhibit wide electronic bands, reflecting the broad, spatially extended nature of 4 d electronic wave functions, with relatively weak electronic correlations, strong crystal field effects and spin-orbit coupling. A feature of many oxides utilised in devices is that they are poised near an instability, such that small changes in environment, temperature or pressure, can result in a structural or electronic phase transition. Understanding the phase transition behaviour can be key to discerning the structure-property relationship and ultimately guide the discovery of ne
