Abstract
The possibility of ferromagnetism in SnO2 is explored by (Fe,TM= Sc, Ti, V, Cr, Mn, and Co) co-doping strategy using ab-initio calculations. Our results revealed that (Fe,Sc), (Fe,V), (Fe,Cr), (Fe,Mn), and (Fe,Co) co-doped SnO2 materials exhibit stable FM ground state, while (Fe,Ti) co-doped system attains the FiM. Furthermore, the calculated magnetic transition temperatures (Tc) show the reasonable range and (Fe,Mn) co-doped system having the highest of 884 K. The most striking feature of the present study is that (Fe,V) co-doped structure displayed the half-metallic behavior with a Tc of 207 K, which makes it promising candidates for potential applications in magnetic memory devices. The V dz2/dxy orbitals are mainly responsible for conductivity in the spin-majority channel with small contributions from Fe 3d. Spin-magnetization density iso-surface plots exhibit that magnetism mainly originated from the admixture of dxy, dxz, and dyz orbitals of Fe/V ions.
