Interface controlled spin filtering and nonreciprocal transport in Altermagnet/Ising superconductor junctions
Arindam Boruah, Saumen Acharjee, Prasanta Kumar Saikia
We investigate theoretically spin-resolved transport, spin filtering, and nonreciprocal effects in an Altermagnet/Ising superconductor (AM/ISC) junction with a spin-active interfac…

Field free Josephson diode effect in Ising Superconductor/Altermagnet Josephson junction
Arindam Boruah, Saumen Acharjee, Prasanta Kumar Saikia
Altermagnets (AMs) are an exotic class of antiferromagnet that exhibit spin-splitting even at the absence of net global magnetization and spin-orbit coupling (SOC) effects. In this…

Nonlinearity in spin dynamics of frustrated Kagomé lattice system under harmonic perturbation
Saumen Acharjee, Arindam Boruah, Reeta Devi +1
In this study, we investigate the spin dynamics of a frustrated Kagomé lattice system, focusing on the nonlinearity of spin oscillations induced by a harmonic magnetic field under…
