Abstract

Hybrid magnetic heterostructures allow the engineering of new material properties by creative uses of proximity effects. When two dissimilar materials are in close physical proximity the properties of each one may be radically modified or occasionally a completely new material emerges. By properly designing hybrid ferromagnet/oxides new magnetic properties arise unlike any known magnetic materials. In a series of recent studies, we have investigated the static and dynamic magnetic properties of different hybrids of ferromagnets and vanadium oxides. The vanadium oxides (VO2 and V2O3) are canonical examples of materials showing a first order structural phase transition and a metal to insulator transformation. Static properties such as the coercivity, anisotropy and magnetization and dynamical properties such as the microwave response are modified by the proximity effects. Our results indicate that the structural transformation and the nanoscale phase coexistence across the first-order phase transition of the oxides are responsible for the observations in these hybrid materials. The results suggest the existence of similar effects in other hybrid materials and give rise to interesting perhaps useful properties.
