Prof. Gerrit Bauer: Spin(calori)tronics with magnetic insulators

Beschreibung

Spintronics based on magnetic and nonmagnetic elemental metals generated functionalities that are employed in nanoscale devices such as switches, memories, and sensors. Ferrimagnetic electric insulators such as man-made yttrium iron garnets form another class of versatile materials, with supreme magnetic quality. K. Uchida, E. Saitoh c.s. demonstrated that they can be actuated thermally and electrically and thereby integrated into conventional electronic and thermoelectric devices, raising the hope for a new and green spintronics. After an elementary introduction into the basic physical concepts, I will review a number of experimental discoveries and theoretical insights on magnetic insulators and its heterostructures with metals.
