Plane Waves in Ferrimagnetics

  • M. S. Sodha

The study of the propagation of plane waves in ferrimagnetics of infinite extent is necessary if one wishes to understand the propagation phenomena in devices (of finite extent). Further, in many practical situations, the wavelength*; is much smaller than the sample size and the waves in regions far (few wavelengths) from the boundaries behave as plane waves. Thus, in this chapter, we discuss the propagation of electromagnetic waves (Section A) and magnetoelastic waves (Section B) in ferrimagnetics of infinite extent.
