After finishing his Ph.D. in 2003 Andrew Ferguson left the University of Cambridge to work at the University of New South Wales in the Centre for Quantum Computer Technology. After 4 years of living by the beach (and learning how to do microwave-frequency, low-temperature experiments) it was time to come home. In 2007 he returned to Cambridge to take up the Hitachi senior research fellowship. Since then, he has built up a spintronics research group that uses microwave techniques to probe a variety of materials and devices.
He is interested in studying novel effects due to electron spins in nanostructures: a topic best called nano-spintronics. His research group aims to explore both classical and quantum spin-effects that are relevant for future technologies. In one recent project, his group has been investigating current induced torques in spin-orbit coupled ferromagnets, and is now extending this to antiferromagnetic materials. In order to perform this research on magnetic dynamics his group had to develop new, ultrasensitive microwave measurement techniques.
