Magnetic Straintronics: Manipulating the magnetization of nanomagnets with strain for both digital and analog applications
Tuesday, 7 Jun
GG Conf. Room
Organized by Electrical Engineering
Abstract: Straintronics is the science and technology of manipulating the magnetic states of magnetostrictive nanomagnets with electrically generated mechanical strain. This talk will describe experimental and theoretical work in my group on switching the magnetization of bistable nanomagnets with strain while dissipating an amount of energy about two orders of magnitude smaller than what state of the art transistors dissipate today. I will also describe some unconventional applications such as simple 2-node Bayesian inference engines, a spin neuron, restricted Boltzmann machines for neural computing, image processing with dipole coupled magnets actuated with time varying strain, simulated annealing with surface acoustic waves, straintronic magnetic tunnel junctions and finally extreme sub-wavelength straintronic nano-antennas whose measured gain and radiation efficiencies exceed those of conventional antennas of the same size by two and five orders of magnitude, respectively.
