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...
Exchange bias (EB) is highly desirable for widespread technologies. Generally, conventional exchange‐bias heterojunctions require excessively large cooling fields for sufficient bias fields, which are generated by pinned spins at the interface of ferromagnetic and antiferromagnetic layers. It is crucial for applicability to obtain considerable exchange‐bias fields with minimum cooling fields. Here,...
