Intrinsic Berry Curvature Driven Anomalous Hall and Nernst Effect in CoMnSn
Bishal Das, Arnab Bhattacharya, Amit Chanda +5
Magnetic topological semimetals often exhibit unusual electronic and thermal transport due to nontrivial bulk band crossings, enabling simultaneous realization of large anomalous H…
Fermi surface nesting driven anomalous Hall effect in magnetically frustrated Mn_2PdIn
Afsar Ahmed, Arnab Bhattacharya, Prashant Singh +5
Noncollinear magnets with near-zero net magnetization and nontrivial bulk electronic topology hold significant promise for spintronic applications, though their scarcity necessitat…
Unconventional anomalous Hall effect in hexagonal polar magnet Y_3Co_8Sn_4
Afsar Ahmed, Jyoti Sharma, Arnab Bhattacharya +5
We report a rare realization of unconventional anomalous Hall effect (UAHE) both below and above the magnetic transition temperature (T_C) in a hexagonal noncentrosymmetric magnet…
Giant Topological Hall Effect in Magnetic Weyl Metal MnPdIrSn
Arnab Bhattacharya, Afsar Ahmed, Sreeparvathy PC +6
The synergy between real and reciprocal space topology is anticipated to yield a diverse array of topological properties in quantum materials. We address this pursuit by achieving…
Spin-Valve-Like Magnetoresistance and Anomalous Hall Effect in Magnetic Weyl Metal MnPdSn
Arnab Bhattacharya, Mohammad Rezwan Habib, Afsar Ahmed +4
Realization of noncentrosymmetric magnetic Weyl metals is expected to exhibit anomalous transport properties stemming from the interplay of unusual bulk electronic topology and mag…
