Research on phase transitions in advanced functional materials is widespread and continues to grow. Scientific interest aside, they are attractive for a wide range of current and future technologies that include computation, medical instrumentation, and energy conversion and storage. During this talk, I will present my work on ferromagnetic, ferroelectric and ferroelastic phase transitions that permit large thermal changes to be driven by changes in magnetic field, electric field or stress field. The resulting magnetocaloric, electrocaloric and mechanocaloric (barocaloric and elastocaloric) effects promise new cooling technologies that are energy efficient and environmentally friendly. The materials that I study include multiferroic materials that possess strong magnetoelectric coupling, which are interesting also for applications in sensors, actuators and data storage.
