Title: Detecting and Controlling the Magnetization Dynamics of Single Nanomagnets
Location: 67-3111 Chemla room
Many emerging spintronics applications will utilize dense arrays of nanomagnetic elements. Device properties depend on both the intrinsic material properties of each element as well as the magnetic environment. Time-resolved magneto-optics provide a means to extract both static and dynamic material parameters and elucidate sub-picosecond dynamic processes. I will review the challenges and capabilities of applying magneto-optic techniques for magnetic characterization of individual nanomagnets, in particular the first observation of single-domain nanomagnet dynamics and the influence of close-by nanostructures on these dynamics. The ability to control the dynamic behavior of a nanomagnet via 3D-shape, orientation, and array geometry will be described.
