DOI: 10.1103/physrevb.98.214422
Abstract: ${\mathrm{Sr}}_{2}{\mathrm{FeOsO}}_{6}$ is an insulating double perovskite compound which undergoes antiferromagnetic transitions at 140 (${T}_{\text{N1}}$) and 67 K (${T}_{\text{N2}}$). To study the underlying electronic and magnetic interactions giving rise to this behavior we have performed inelastic… read more here.
