Hybrid materials 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. In the area of magnetism, controlling the
magnetic properties of ferromagnetic thin films without magnetic fields is an ongoing
challenge with multiple technological implications for low- energy
consumption memory and logic devices. Interesting possibilities include
ferromagnets in proximity to dissimilar materials such as antiferromagnets or
oxides that undergo metal-insulator transitions. In a series of recent studies, we
have investigated the properties of different hybrids between oxides, which
undergo metal-insulator and structural phase transitions and other elemental
or complex materials. Both the static as well as dynamical properties of the
ferromagnets are drastically affected. The static and dynamical properties are
clearly modified by the proximity effect and give raise to interesting perhaps
useful properties.
