Solid state physics


SVOWe have improved the sythesis technics to get ultra pure ceramics of Sr2VO4 material. Performing optics, transport and structural analysis, we have demonstrated that the material undergoes an exotic complex series of spin-orbital transitions.

We have developped a crystal growth technics based on the levitating crucible. We have grown many ternary silicides like MnCoSi, CoNiSi, FeCoSi and investigated different aspects of structural and magnetic phase diagram.

We have been precursors in the extraction of the electron-phonon coupling function from optical spectroscopy measurements. Our work on borides was both on an experimental side but we have also calculated the band structure of the material and computed the optical conductivity and the de Haas–van Alphen cross sections.
