Signature of topological non-trivial band structure in TaSiTe
Shubhankar Roy, Ratnadwip Singha, Arup Ghosh +1
The study of topology protected electronic properties is a fascinating topic in present day condensed matter physics research. New topological materials are frequently being propos…
Anomalous Hall effect in half-metallic Heusler compound CoTi (=Si, Ge)
Shubhankar Roy, Ratnadwip Singha, Arup Ghosh +2
Though Weyl fermions have recently been observed in several materials with broken inversion symmetry, there are very few examples of such systems with broken time reversal symmetry…
Lattice dynamics of topological Dirac semimetal LaAgSb with charge density wave ordering
Ratnadwip Singha, Sudeshna Samanta, Tara Shankar Bhattacharya +5
LaAgSb is a rare material, which offers the opportunity to investigate the complex interplay between charge density wave (CDW) ordering and topology protected electronic band…
Complex exchange mechanism driven ferromagnetism in half-metallic Heusler CoTiGe: Evidence from critical behavior
Shubhankar Roy, Nazir Khan, Ratnadwip Singha +2
We have investigated the critical phenomenon associated with the magnetic phase transition in the half-metallic full-Heusler CoTiGe. The compound undergoes a continuous ferroma…
Magnetotransport properties and giant anomalous Hall angle in half-Heusler compound TbPtBi
Ratnadwip Singha, Shubhankar Roy, Arnab Pariari +2
Magnetic lanthanide half-Heuslers (PtBi; being the lanthanide) represent an attractive subgroup of the Heusler family and have been identified as ideal candidates for time r…
Planar Hall effect in type II Dirac semimetal VAl
Ratnadwip Singha, Shubhankar Roy, Arnab Pariari +2
The study of electronic properties in topological systems is one of the most fascinating topics in condensed matter physics, which has generated enormous interests in recent times.…
