Magnetic criticality and magnetocaloric response in MnBiTe and MnBiTe
Nazma Firdosh, Shreyashi Sinha, Sujit Manna
MnBiTe and MnBiTe are antiferromagnetic topological insulators belonging to the MnBiTe series, where structural layering provides a natural route to…
Nanoscale Electronic Phase Separation Driven by Fe-site Ordering in Fe\textsubscript{5-x}GeTe\textsubscript{2}
Shreyashi Sinha, Ayan Jana, Suchanda Mondal +3
Understanding how local structural order governs electronic correlations is essential for revealing the microscopic mechanism underlying emergent behavior in two-dimensional magnet…
Imaging Quantum Well States of Dirac Electrons in Exfoliated 3D Topological Insulators
Shreyashi Sinha, Shantanu Pathak, Saswata Bhattacharya +1
We present a controlled mechanical exfoliation technique for bulk 3D topological insulators that yields atomically clean ultrathin flakes, enabling quantum well states (QWS) of Dir…
Intertwined magnetic phase driven exchange bias and its impact on the anomalous Hall effect in MnBiTe
Nazma Firdosh, Shreyashi Sinha, Indraneel Sinha +3
We report on the interplay between atomic scale inhomogeneity and competing magnetic phases and its effect on the anomalous Hall effect in the layered antiferromagnet MnBiTe$_7…
Occurrence of chemically tuned spin-texture controlled large intrinsic anomalous Hall effect in epitaxial thin Films
Indraneel Sinha, Saurav Sachin, Shreyashi Sinha +3
Achieving atomically flat and stoichiometric films of chiral antiferromagnets (AFM) with two-dimensional kagome spin lattice structures are crucial for integrating these materials…
Anomalous Hall effect in highly c-plane oriented MnGe/Si(100) thin films grown by pulsed laser deposition
Indraneel Sinha, Purba Dutta, Nazma Firdosh +3
Antiferromagnetic MnGe with a non-collinear Kagome structures present exciting prospects for exploring Berry curvature driven anomalous Hall effects (AHE). Despite substantia…
