Abstract
Employing first principles density functional calculations, together with solution of the low-energy, model Hamiltonian constructed in a first principles manner, we explored the origin of magnetism and the Tc trend in Cr-based double perovskite series, Sr2CrB'O6 (B'= W/Re/Os). Our study shows that the apparently puzzling Tc trend in Sr2CrB'O6 (B'= W/Re/Os) series can be understood in terms of the interplay of the hybridization driven mechanism and the superexchange mechanism.
