Magnetism of doped Metal Halide Perovskites.

Abstract
We investigate the effect of transition metal doping of BaZrS3 and HfSnS3 as a prototype of new DMS material. BaZrS3, a prototypical chalcogenide perovskite semiconductor shows room temperature ferromagnetism upon doping by Mn and Fe elements. Density Functional calculations of exchange coupling in the system show substantial increase in exchange coupling strength upon electron doping due to the presence of Sulphur vacancies. We present a model of exchange coupling mediated by electrons when conduction band has mainly d-character.
