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…
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…
