Hybrid Magnetic Heterostructures
Written by Maria Torres Arango
Proximity effects in magnetic heterostructures are of interest because of the unprecedented properties that these materials possess. Particularly the metal-insulator switching behavior characteristic of ferromagnet/antiferromagnet and ferromagnet/metal-oxide stacks upon temperature variation. Specifically, the latter group of heterostructures including metal-oxides is of importance because of the stability, abundance, and broad range of phases that metal-oxides exhibit. Nevertheless, these materials also exhibit defects in their structure that present significant challenges in the materials performance. In his enthusiastic talk, Ivan Schuller shared his research group’s efforts focusing on magnetic heterostructures, exploring multiple phases of vanadium oxides-Ni, Co, and Fe assemblies, where he emphasized the opportunities of these structures for both applied and basic research. His invitation is to embrace the defects in metal-oxides to advance science and make robust systems that may enable novel applications and capabilities in the neuromorphic computing field.
