Bulk photovoltaic effect in MoSe $_{2}$ 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 $_{2}$ and Janus MoSSe. Two Janus configurations are considered…

Atypical Ferrimagnetism in Ni $_{4}$ Nb $_{2}$ O $_{9}$

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 $M n_{3 + x} P t_{1 - x}$ 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…
