Unraveling hidden Raman modes in -MnTe: Effects of long-range dipole-dipole interactions on phonon bands
Susmita Jana, Rajib Sarkar, Dhavala Suri +1
In this study, we address the seemingly open question of disparity between the experimentally and theoretically observed Raman spectra for the altermagnetic -MnTe. We establish…
Nature of the 175-180 cm Raman Feature in Altermagnetic -MnTe
Pankaj Bhardwaj, Rajib Sarkar, Naresh Shyaga +6
The 175 cm Raman mode in -MnTe has long been assigned to the material's only symmetry-allowed phonon (), yet first-principles calculations consistently place this…
Unified Transport and Susceptibility Analysis of a Thin BSCCO Film: From Local Pairing to Global Phase Coherence
Santu Prasad Jana, Bismaya Ranjan Nayak, Sohini Guin +3
The superconducting transition in thin high- films can be significantly broadened by disorder, spatial inhomogeneity, and phase fluctuations. Here, we study the transition in…
Barium Hexaferrite Thin Films as a Scalable Magnetic-Insulator Platform for Proximity-Engineered Spintronics
Shyam Sundar Poriah, Sanjana D. S., Agrim Sharma +8
Rare-earth iron garnets, such as yttrium iron garnet (YIG) and thulium iron garnet (TmIG), are the benchmark magnetic insulators for spintronic and magnonic devices, but achieving…
Berry Curvature Driven Transport in Silicon-Compatible Altermagnetic -MnTe Thin Films
Rajib Sarkar, Subhransu Kumar Negi, Arindom Das +10
Integrating spin-dependent functionality with mainstream semiconductor technology is a central goal of modern spintronics, yet most candidate materials remain incompatible with sil…
Vortex Dynamics Driven Transverse Transport in Superconducting Thin Films
Laxmipriya Nanda, Sohini Guin, Yasen Hou +7
The generation of transverse voltage in superconducting thin films carrying a longitudinal current has been recently related to demonstrate exotic, symmetry-breaking transport phen…
Crystallographic Orientation-Dependent Magnetotransport in the Layered Antiferromagnet -- CrSBr
Naresh Shyaga, Pankaj Bhardwaj, Rajib Sarkar +3
Among two-dimensional magnetic materials, CrSBr has attracted considerable attention owing to its coexistence of ferromagnetic and antiferromagnetic ordering, which depends sensiti…
Nitrogen-Vacancy-Mediated Magnetism in Sputtered GdN Thin Films
Pankaj Bhardwaj, Jyotirmoy Sarkar, Bubun Biswal +11
Among rare-earth nitrides (RENs), gadolinium nitride (GdN) stands out as a promising material for spintronics owing to its distinctive combination of semiconducting behavior, stron…
Magneto-Chiral Anisotropy in Josephson Diode Effect of All-Metallic Lateral Junctions with Interfacial Rashba Spin-Orbit Coupling
Maximilian Mangold, Lorenz Bauriedl, Johanna Berger +7
We explore the role of interfacial Rashba spin-orbit coupling (SOC) for the Josephson diode effect in all-metal diffusive Josephson junctions. Devices with Fe/Pt and Cu/Pt weak lin…
Time Reversal Symmetry Broken Electronic Phases in Thin Films of BiSrCaCuO
Sohini Guin, Naresh Shyaga, Jagadish Rajendran +6
High-temperature superconductors (high-Tc SCs) host a rich landscape of electronic phases encompassing the pseudogap, strange metal, superconducting, antiferromagnetic insulating,…
Tracing Dirac points of topological surface states by ferromagnetic resonance
Laura Pietanesi, Magdalena Marganska, Thomas Mayer +13
Ferromagnetic resonance is used to reveal features of the buried electronic band structure at interfaces between ferromagnetic metals and topological insulators. By monitoring the…
Enhanced Ferromagnetism in Monolayer Cr2Te3 via Topological Insulator Coupling
Yunbo Ou, Murod Mirzhalilov, Norbert M. Nemes +20
Exchange-coupled interfaces are pivotal in exploiting two-dimensional (2D) ferromagnetism. Due to the extraordinary correlations among charge, spin, orbital and lattice degrees of…
