THURSDAY, APRIL, 14, 2022 11:00AM-11:50AM

Abstract: Nanomagnets form the basis of emerging spintronic devices in data storage and memory, and their dynamic magnetization properties are critical parameters for applications. Recently, the interaction between magnetic and mechanical oscillations via magneto-elastic coupling has been gaining attention. I will discuss the influence of mechanical vibrations in nanopatterned structures on the magnetic properties and behavior of individual nanomagnets. Examples include the use of surface acoustic waves for cold excitation of magnetization dynamics to extract intrinsic material parameters and the first observation of strong coherent coupling between phonons and magnons within a single magnetic element.
