Interplay of spin-lattice and electronic coupling far above Neel ordering in 2D antiferromagnetic CrPS4 and its interface manifestation
Divya Jangra, Binoy Krishna De, Mukesh Kumar Dasoundhi +13
A short-range spin correlation driven, strongly intercoupled spin-phonon-electronic state far above TN (~38K) is identified in the low dimensional van der Waals antiferromagnet CrP…
Semi-Dirac States and Quantum Linear Magnetoresistance in Helimagnetic Pnictide MnP
Prasanta Chowdhury, Jyotirmoy Sau, Sanat Kumar Adhikari +7
Large linear positive magnetoresistance (LPMR) in topological and magnetic materials remains a subject of intense debate, particularly in noncollinear spin systems where spin-depen…
Charge transfer and competing symmetry breaking drive orbital reconstruction and emergent ferromagnetism in insulating oxide superlattices
Nandana Bhattacharya, Ranjan Kumar Patel, Siddharth Kumar +13
Electron correlation, hopping, and ligand-to-metal charge transfer collectively lead to diverse electronic and magnetic phenomena in 3 transition-metal oxides, where directional…
Antisite-disorder driven tuning of magnetic properties and exchange-bias in NdSrCoMnO () double perovskites
Kazi Parvez Islam, Jayjit Kumar Dey, Sourav Chowdhury +8
We demonstrate precise control of exchange bias (EB) in the NdSrCoMnO () double-perovskite series through Sr induced hole doping, unveil…
Topological spin-texture transitions in van der Waals magnets revealed by X-ray Fourier transform holography
Sourav Chowdhury, Soumyaranjan Dash, Michael Schneider +14
Nontrivial topological spin-textures, such as skyrmions, merons, bimerons, and skyrmioniums, are envisioned as robust building blocks for future memory and logic devices. Controlla…
Coupled phase transitions in crystalline solids with extreme chemical disorder
Subha Dey, Rukma Nevgi, Suresh Chandra Joshi +13
Structural phase transitions often couple to magnetic and electronic degrees of freedom, enabling emergent phenomena in solids. In high-entropy oxides (HEOs), which typically stabi…
Vector Spin Chirality Switching in Noncollinear Antiferromagnets
Aritra Dey, R. Bhuvaneswari, Sourav Chowdhury +14
Spin chirality provides a powerful route to control magnetic and topological phases in materials, enabling next-generation spintronic and quantum technologies. Coplanar noncollinea…
