This thesis reports on some recent results in the field of acoustics and magnonics.
Chapter 1 reviews the literature on magnonics and GHz frequency transducers, and highlights the lack of understanding of the growth mechanism of magnetron sputtered ZnO thin films. A novel configuration for exciting magnetostatic spinwaves using ZnO transducers is proposed.
Chapter 2 is an introduction to piezoelectricity and how it can be used to generate GHz acoustic waves. A detailed fo...Expand abstract
