A composite system comprising of two ferrimagnetic oxide compounds, a spinel and a garnet, has been investigated. A series of materials with varying proportion of the contents of magnesium manganese ferrite and yttrium iron garnet, both of quality suitable for microwave applications, have been prepared and studied in relation to the parent materials. Results obtained from examination of samples by XRD and EPMA coupled with electrical and magnetic measurements have been used to understand the observed behaviour.
