摘要

Double Perovskites In article number 2209759, Zheng Deng, Martha Greenblatt, Changqing Jin, and co-workers report that a cooling field of a few Oersteds can generate a giant exchange bias like effect in a double perovskite, Y2NiIrO6. This fascinating bias effect is attributed to the pinned magnetic domains due to the combination of strong spin–orbit coupling on Ir, and antiferromagnetically coupled Ni- and Ir-sublattices.
