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…

Mean field magnetism and spin frustration in a double perovskite oxide with compositional complexity

Nandana Bhattacharya, Ravi Kiran Dokala, Sourav Chowdhury +9

The rise of high-entropy oxides as a major functional materials design principle in recent years has prompted us to investigate how compositional disorder affects long-range magnet…
