In-plane anomalous and third-harmonic Hall response in an easy-plane trigonal magnet
Arnab Das, Soumik Mukhopadhyay
We report the emergence of an in-plane anomalous Hall effect (IPAHE) and a pronounced third-harmonic Hall response in an easy-plane trigonal magnetic system achieved via tuning of…
Junction-free polarity-tunable superconducting diode effect enables XNOR logic operation
Alapan Bera, Soumik Mukhopadhyay
The realization of the superconducting diode effect (SDE), characterized by non-reciprocal supercurrent, is a major step towards dissipationless logic circuits. A polarity-tunable…
Angle dependent hysteretic magnetotransport in MnBi2Te4 nanoflakes
Tithiparna Das, Soumik Mukhopadhyay
Controlling magnetic phases in two-dimensional systems, where charge transport is highly sensitive to real-space spin inhomogeneities, is central to understanding emergent magnetic…
