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…
Chiral orbital current driven topological Hall effect in Mn3Si2Te6
Arnab Das, Soumik Mukhopadhyay
Chiral orbital current (COC) plays a crucial role in governing the magnetization and transport behaviour in the layered ferrimagnetic nodal-line semiconductor Mn3Si2Te6. Here, we o…
Room temperature intrinsic anomalous Hall effect in disordered half-metallic ferromagnetic quaternary Heusler alloy CoRuFeSi
Manikantha Panda, Sonali S. Pradhan, Prabuddha Kant Mishra +6
Quaternary Heusler alloys offer a versatile platform for engineering magnetic and topological transport phenomena through chemical flexibility and tunable disorder. Here, we report…
Disorder-driven Weyl-Kondo Semimetal Phase in WTe
Arpan Manna, Sunit Das, Amit Agarwal +1
In this Letter, we report the observation of disorder-driven anisotropic Kondo screening and spontaneous Hall effect in bulk WTe, a nonmagnetic type-II Weyl semimetal. We sho…
Common topological origin of longitudinal and transverse magnetoresistance in Fe3GeTe2
Alapan Bera, Soumik Mukhopadhyay
In this work, we reveal the coexistence and correlation of a topological cusp anomaly in the planar Hall signal and a spin-flip scattering dominated positive longitudinal magnetore…
Tuning the chiral orbital currents in a colossal magnetoresistive nodal line ferrimagnet
Arnab Das, Soumik Mukhopadhyay
The ferrimagnetic nodal-line semiconductor MnSiTe exhibits colossal magnetoresistance (CMR) owing to the chiral orbital currents (COC). The COC is developed due to spin…
