UNSW researchers discover strange magnetic properties of quantum confined 'holes' in a semiconductor
A new paper by LaReine Yeoh, Ashwin Srinivasan, Oleh Klochan and co-authors reveals new and strange magnetic properties of quantum confined holes. The researchers have shown that a magnetic field applied in one direction can generate a spin polarisation of holes at right angles to the applied magnetic field, which is quite different behaviour than for similar electron systems. This work has been published in Physical Review Letters, and may have applications for future spin based electronics and quantum information.
