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…
Disorder-mediated quenching of magnetization in NbVTiAl: Theory and Experiment
Deepika Rani, Jiban Kangsabanik, K. G. Suresh +1
In this paper, we present the structural, electronic, magnetic and transport properties of a equiatomic quaternary alloy NbVTiAl. The absence of (111) and (200) peaks in X-ray diff…
