Unconventional topological phase transition from semimetal to insulator in SnBi2Te4: Role of anomalous thermal expansion
T. K. Dalui, B. Das, C. K. Barman +8
We propose SnBi2Te4 to be a novel candidate material exhibiting temperature (T) mediated transitions between rich topological phases. From a combined theoretical and experimental s…
Weak antilocalization effect and triply degenerate state in Cu-doped CaAuAs
Sudip Malick, Arup Ghosh, Chanchal K. Barman +4
The effect of 50\% Cu doping at the Au site in the topological Dirac semimetal CaAuAs is investigated through electronic band structure calculations, electrical resistivity, and ma…
Colossal Anomalous Hall Conductivity and Topological Hall Effect in Ferromagnetic Kagome Metal NdAl
Durgesh Singh, Jadupati Nag, Sankararao Yadam +3
Historically, the genesis of anomalous Hall effect (AHE) in magnetic materials has always been a fascinating yet controversial topic in the solid state physics community. Recent pr…
Hidden and coexistent magnetic phases in Kondo-type Cerium Hexaboride (CeB6)
C. K. Barman, Prashant Singh, D. D. Johnson +1
The heavy fermion material CeB6 shows hidden magnetic ordered phases. Besides well-known Ferromagnetic(FM) and Antiferromagnetic(AFM) phases, CeB6 is speculated to form a unique an…
