Ab Initio Calculation of the System Cr–GaSb: A New High-Pressure Phase Containing Defects

Article Preview

Abstract:

We report on ab initio density-functional calculations of a novel spintronics-related compound CrGa2Sb2 recently synthesized under high pressure. The effect of Cr deficiency on the electronic, magnetic and optical properties of CrGa2Sb2 is considered. New X-ray structural measurements up to high pressure of 9 GPa are presented.
