Motivation and Introduction to Theory,This chapter introduces the motivation for this thesis: the need to avoid the stagnation of technological progress by investigating alternative computing paradigms, namely magnon-based computing. An introduction to the field of magnonics and magnon behaviour is presented, followed by a brief introduction to nonlinear behaviour.

Magnonic Phase Conjugation Experiment,This chapter describes an experimental investigation concerning the realisation of a phase conjugate mirror via four-wave mixing created in a spin wave system. It is demonstrated through experiments and simulations that the mirror is at its most reflective when a standing spin wave is present across the width of the magnon waveguide.

Investigating Nonlinear Effects,This chapter investigates a time-domain fractal arising from the spatio-temporally periodic potential that occurs as a result of the standing wave. The onset of great-granddaughter fractal modes is observed and the frequency dependence of the amplitude of the fractal modes is discussed.

Concluding Remarks,This chapter offers concluding remarks, and considers future experiments that may develop the field.
