Discovery - Video
Video shows the atomic and spin structure of chromia and the ferromagnetic thin film on top.

This movie is based on a cartoon of the project researchers' heterostructure showing the atomic and spin structure of chromia and the cobalt palladium (CoPd) ferromagnetic thin film on top. Electric fields are "measured" by a multimeter and applied via electrodes (dark yellow films) sandwiching the heterostructure. The applied voltages are displayed on the multimeter. While the movie progresses the voltages change from 0 to +1.5kV then back to -1.7kV. A small constant magnetic field is applied in the direction indicated by the blue arrow simultaneously with the applied electric fields. The primary objective of the movie is to show a switching event of the magnetic hysteresis of the CoPd film which sets in at about 1.4kV. It is this electrically controlled of the magnetization which makes the finding highly relevant for spintronic applications. In addition to the pronounced switching effect we show largely exaggerated the electrically controlled exchange bias due to the linear magnetoelectric effect of chromia.
