Antiferromagnets (AFMs) with zero net magnetization are proposed as active elements in future spintronic devices. Depending on the critical thickness of the AFM thin films and the measurement temperature, bimetallic Mn-based alloys and…

The list of materials systems displaying both electric and magnetic long range order is short. Oxides, however, concentrate numerous examples of multiferroicity with, in some cases, a large magnetoelectric coupling. As a result, a fruitful…
