Deterministic Switching in Altermagnets via Asymmetric Sublattice Spin Current
Sayan Sarkar, Sunit Das, Amit Agarwal
We demonstrate a deterministic switching mechanism in collinear altermagnets driven by asymmetric sublattice spin currents. Unlike conventional antiferromagnets, where combined par…

Spin band geometry drives intrinsic thermal spin magnetization and current
Sankar Sarkar, Harsh Varshney, Sayan Sarkar +1
Generating spin magnetization and spin currents without magnetic or electric fields is a key frontier in spin caloritronics. Spin responses driven by thermal gradients offer a prom…

Symmetry-driven Intrinsic Nonlinear Pure Spin Hall Effect
Sayan Sarkar, Sunit Das, Amit Agarwal
The generation of pure spin current, spin angular momentum transport without charge flow, is crucial for developing energy-efficient spintronic devices with minimal Joule heating.…
