Recent developments and the future perspectives in magnetoelectric nanocomposites for memory applications

This Perspective highlights the promise of magnetoelectrics for potential memory and other applications, e.g., sensors and energy harvesters, noting the challenges posed by current magnetoelectric materials and potential solutions to these challenges. While single phase materials do give strong enough magnetoelectric coupling, interface coupled composite systems show unique advantages. From the viewpoint of these composite materials and devices, we review the current status and present an outlook on possible future research directions, with particular emphasis on 3-1 type nanocomposites which are arguably the most promising composite form.
