Magnetic cooling provides an alternative refrigeration method that is more energy efficient than standard refrigeration technologies, and magnetocaloric materials have proven to be some of the best candidate materials for magnetic cooling. In an effort to make magnetocaloric materials a viable option for refrigeration, alternative methods of driving the magnetocaloric effect, specifically with voltage and stress, are analyzed through simulations and experiments on two hybrid material devices. The results indicate that the concept of voltage induced stress to drive the magnetocaloric effect is plausible. Further materials research is required to find a material combination that can compete with existing refrigeration technology.born digitalmasters thesesengCopyright of the original work is retained by the author.magnetocaloric effectphase transitionvanadium dioxidemagnetostrictionmagnetic refrigerationPZTTextEmbargo Expires: 07/08/2020
