New insights into the magnetic properties of the Ca2Fe2O5 ferrite

Correlation between the EPR signal intensity (area), the Fe3O4 amount (weight %) from XRPD (left y-axis) and the saturation magnetization values (M0) determined from magnetic measurements (right y-axis) for all the Ca2Fe2O5 samples. A linear interpolation of the M0 values vs. the EPR signal intensity is also reported.
