Outline of Final Research Achievements

In this project, we have studied the possibility of synthesizing novel oxyhydride perovskites materials via the use of high pressure synthesis. We have shown that high pressure allows yielding novel structures containing transition metals that cannot be formed via ambient pressure techniques. Among the structures discovered is a stoichiometric disordered SrCrO2H. Interestingly, this cubic framework presents the highest Neel temperature observed in chromium oxides in reason of the lack of structural distortions. High pressure synthesis is therefore an interesting path towards forming novel oxyhydrides and possibly reach exotic properties.
