Combination of two quantum materials achieves unprecedented control over electron spin (IMAGE)
Caption
By placing a magnetic material on top of a topological material, the researchers were able to switch magnetization using very small electrical currents, and without applying an external magnetic field. The interface between the two materials is perfectly smooth and creates an ideal connection without “friction” or defects. This allows spin information to be transferred between the materials without being weakened or disturbed.
