Correlation between the exchange bias effect and antisite disorders in Sr $_{2 - x}$ La $_{x}$ CoNbO $_{6}$

Ajay Kumar, B. Schwarz, R. S. Dhaka

We unravel the effect of La substitution and hence antisite disorders on the exchange bias (EB) mechanism in Sr $_{2 - x}$ La $_{x}$ CoNbO $_{6}$ ( $x =$ 0, 0.2) double perovskite samples using…
