Comparative study of FeCr2S4 and FeSc2S4: Spinels with orbitally active A site
S. Sarkar, T. Maitra, Roser Valentí +1
Using first-principles density functional calculations, we perform a comparative study of two Fe based spinel compounds, FeCr2S4 and FeSc2S4. Though both systems contain an orbital…

Cooperative orbital ordering and Peierls instability in the checkerboard lattice with doubly degenerate orbitals
R. T. Clay, H. Li, S. Sarkar +2
It has been suggested that the metal-insulator transitions in a number of spinel materials with partially-filled t_2g d-orbitals can be explained as orbitally-driven Peierls instab…

Proposed Orbital Ordering in MnV2O4 from First-principles Calculations
S. Sarkar, T. Maitra, Roser Valenti +1
Based on density functional calculations, we propose a possible orbital ordering in MnV2O4 which consists of orbital chains running along crystallographic a and b directions with o…
