Topological Hall effect in the antiferromagnetic Dirac semimetal EuAgAs
Antu Laha, Ratnadwip Singha, Sougata Mardanya +4
The non-trivial magnetic texture in real space gives rise to the intriguing phenomenon of topological Hall effect (THE), which is relatively less explored in topological semimetals…
Magnetotransport properties of the topological nodal-line semimetal CaCdSn
Antu Laha, Sougata Mardanya, Bahadur Singh +4
Topological nodal-line semimetals support protected band crossings which form nodal lines or nodal loops between the valence and conduction bands and exhibit novel transport phenom…
Topological Dirac Semimetal Phase in Bismuth Based Anode Materials for Sodium-Ion Batteries
Wei-Chi Chiu, Bahadur Singh, Sougata Mardanya +7
Bismuth has recently attracted interest in connection with Na-ion battery anodes due to its high volumetric capacity. It reacts with Na to form NaBi which is a prototypical Dir…
Magnetic field-dependent resistance crossover and logarithmic to non-saturating magnetoresistance in topological insulator BiTe
Anand Nivedan, Kamal Das, Sandeep Kumar +4
We report a metal-insulator like transition in single crystalline 3D topological insulator Bi2Te3 at a temperature of 230K in presence of an external magnetic field applied normal…
Prediction of three-fold fermions in a nearly-ideal Dirac semimetal BaAgAs
Sougata Mardanya, Bahadur Singh, Shin-Ming Huang +5
Materials with triply-degenerate nodal points in their low-energy electronic spectrum produce crystalline-symmetry-enforced three-fold fermions, which conceptually lie between the…
Intrinsic magnetism in monolayer transition metal trihalides: a comparative study
Shalini Tomar, Barun Ghosh, Sougata Mardanya +5
Two dimensional magnetic materials, with tunable electronic properties could lead to new spintronic, magnetic and magneto-optic applications. Here, we explore intrinsic magnetic or…
