Evolving Devil's staircase magnetization from tunable charge density waves in nonsymmorphic Dirac semimetals
Ratnadwip Singha, Tyger H. Salters, Samuel M. L. Teicher +4
While several magnetic topological semimetals have been discovered in recent years, their band structures are far from ideal, often obscured by trivial bands at the Fermi energy. S…
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…
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…
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…
