Intrinsic Gyrotropic Magnetic Current of Orbital Origin
Koushik Ghorai, Sankar Sarkar, Amit Agarwal
In gyrotropic crystals, an oscillating magnetic field induces a charge response known as the gyrotropic magnetic current. While its conventional origin is attributed to magnetic fi…

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…

Spin-split magnon bands induce pure spin current in insulating altermagnets
Sankar Sarkar, Amit Agarwal
Altermagnets offer a promising platform for dissipationless spin transport by combining zero net magnetization with spontaneous non-relativistic spin splitting. However, their magn…
