Bismuth Films on EuO(111) as a Platform for Proximity-Induced Topological States
Subham Naskar, Sujit Manna
Interfacing two-dimensional bismuth with a magnetic layer provides a promising route towards realizing higher-order topological phases. In particular, bismuthene on a ferromagnetic…
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…
Altermagnetic Superconducting Diode Effect in MnPt/Nb Heterostructures
Saurav Sachin, Mathias S. Scheurer, Constantin Schrade +1
Compensated magnetic orders that can split the spin-degeneracy of electronic bands have become a very active field of research. As opposed to spin-orbit coupling, the splitting res…
Altermagnetic superconducting diode effect from non-collinear compensated magnetism in MnPt
Constantin Schrade, Sujit Manna, Mathias S. Scheurer
Altermagnets have recently emerged as a distinct class of magnetic systems that exhibit spin splitting of electronic bands while retaining zero net magnetization. This unique combi…
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…
