MICROWAVE PROPERTIES OF PARTIALLY MAGNETIZED FERRITES

Abstract

The microwave properties of partially magnetized materials have been investigated. The real parts of the components of the permeability tensor have been measured as a function of the ratios of saturation magnetization to angular frequency and average magnetization to angular frequency and location on the magnetic hysteresis loop on a yttrium iron garnet (YIG) and magnesium manganese ferrite (MgMnF). The high power threshold has been measured on YIG as a function of sample shape, the polarization of the rf magnetic field and the orientation of the rf field to the static magnetization. The Suhl and Schloemann theories for high power non-linearity have been extended to include arbitrary ellipsoids, linearly polarized rf magnetic field, anti-Larmor circularly polarized rf magnetic field, and arbitrary orientation between the rf magnetic field and the static magnetization.
