Bulk photovoltaic effect in MoSe and Janus MoSSe sliding ferroelectrics
Roumita Roy, Giuseppe Cuono, Silvia Picozzi
We present a first-principles study of the nonlinear optical properties of sliding ferroelectric bilayers based on MoSe and Janus MoSSe. Two Janus configurations are considered…
Atypical Ferrimagnetism in NiNbO
Jhuma Sannigrahi, Roumita Roy, Richard Waite +6
Ferrimagnetism typically emerges from chemically distinct magnetic ions or the same element at two inequivalent crystallographic sites, rendering unequal moments. In contrast, Ni4N…
Occurrence of chemically tuned spin-texture controlled large intrinsic anomalous Hall effect in epitaxial thin Films
Indraneel Sinha, Saurav Sachin, Shreyashi Sinha +3
Achieving atomically flat and stoichiometric films of chiral antiferromagnets (AFM) with two-dimensional kagome spin lattice structures are crucial for integrating these materials…
Electronic and magnetic ground state of 4 double perovskite ruthenates ALaRuO (A Ca, Sr, Ba)
Asha Ann Abraham, Roumita Roy, Ruta Kulkarni +2
4 transition metal oxide (TMO) offers an intriguing puzzle for their electronic and magnetic ground state. They are in the cross-over regime of strong spin orbit interaction (SO…
Extrinsic to intrinsic mechanism crossover of anomalous Hall effect in the Ir-doped MnPtSn Heusler system
Sk Jamaluddin, Roumita Roy, Amitabh Das +2
Recent findings of large anomalous Hall signal in nonferromagnetic and nonferrimagnetic materials suggest that the magnetization of the system is not a critical component for the r…
Structure, magnetism and electronic properties in 3-5 based double perovskite (SrCa)FeIrO (0 1): A combined experimental and theoretical investigation
K. C. Kharkwal, Roumita Roy, Harish Kumar +6
The 3-5 based double perovskites offer an ideal playground to study the interplay between electron correlation () and spin-orbit coupling (SOC) effect, showing exotic phys…
