Stacking-dependent magnetic ordering in bilayer ScI
Soumyajit Sarkar, Soham Chandra
Stacking-dependent magnetism in two-dimensional van der Waals materials offers an effective route for controlling magnetic order without chemical modification. Here, we present a c…
Electronic correlation, magnetic structure and magnetotransport in few-layer CrI3
Soumyajit Sarkar, Peter Kratzer
Using density functional theory combined with a Hubbard model (DFT+U ), the electronic band structure of CrI3 multilayers, both free-standing and enclosed between graphene contacts…
Probing the Orbital Origin of Conductance Oscillations in Atomic Chains
Ran Vardimon, Tamar Yelin, Marina Klionsky +4
We investigate periodical oscillations in the conductance of suspended Au and Pt atomic chains during elongation under mechanical stress. Analysis of conductance and shot noise mea…
Signature of an antiferromagnetic metallic ground state in heavily electron doped Sr2FeMoO6
Somnath Jana, Carlo Meneghini, Prabuddha Sanyal +4
SrFeMoO is a double perovskite compound, known for its high temperature behavior. Combining different magnetic and spectroscopic tools, we show that this compound can be…
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…
