Research Interests

My research is focused on the theoretical investigation of electronic and magnetic properties of complex novel materials (mostly, but not limited, rare-earth compounds) through first principles methods.

  • X-ray magnetic circular dichroism & X-ray magnetic resonant scattering
  • Iron-Arsenic based superconductivity
  • Structure and magnetic phase transition
  • Shape memory and martensitic phase transition
  • Hard materials and elastic properties
