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 $d$ transition-metal oxides, where directional…

Antisite-disorder driven tuning of magnetic properties and exchange-bias in Nd $_{2 - x}$ Sr $_{x}$ CoMnO $_{6 - δ}$ $(0 \leq x \leq 1)$ ( $δ \sim 0.5$ ) double perovskites

Kazi Parvez Islam, Jayjit Kumar Dey, Sourav Chowdhury +8

We demonstrate precise control of exchange bias (EB) in the Nd $_{2 - x}$ Sr $_{x}$ CoMnO $_{6 - δ}$ ( $0 \leq x \leq 1$ ) double-perovskite series through Sr $^{2 +}$ induced hole doping, unveil…
