Abstract : The properties of magnetoelastic Love waves in the simplest structure are reviewed. The theory and properties of magnetoelastic Love waves in epitaxial magnetic films are described. Certain properties are shown to be nonreciprocal. The conditions necessary to obtain parallel pumped parametric excitation of magnetostatic surface waves are found and these conditions discussed. Experiments with loaded Rayleigh waves in CdS layered YIG are described. These experiments extend to 415 MHz, the upper frequency at which surface waves in layered substrates have been generated, propagated and detected. The reciprocal interaction of these loaded Rayleigh waves with volume magnetostatic waves is discussed. (Author)
