Abstract:
The aim of our present work is to study the effect of tetravalent ions substitution on Cu-ferrite properties. The first system is of the chemical formula Cu1+x Gex Fe2-2x O4 for Ge4+ substitution. Mean while the second system is of the formula Cu1+x Six F1. X-ray diffraction analysis was used to confirm that the samples were formed in single phase spinel structure.2. Measurements of magnetization and hystersis loops at room temperatures were carried out.3. Measurements of hystersis loops and initial permeability at different temperatures were carried out.
