Abstract [en]

In this thesis we present a fluid model for plasmas which include spin contributions. Also, how to use the model is discussed. We then consider non-linear theories, such as coupled mode theory. The main theory considered is the Manley-Rowe relations for the coupling coefficients. It is easier to work with wave energy densities rather than amplitudes to show Manley-Rowe relations. Manley-Rowe relations are used, both as a test for a theory, showing that the theory has an underlying Hamiltonian structure, and when considering parametric instabilities of the waves. We define a linearised wave energy density for spin plasmas and demonstrate a Manley-Rowe relation for a given geometry for the waves.
