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…
