Notes:
The distribution of the critical field of nontextured polycrystalline ferrite is determined. Barium ferrite samples are saturated in one direction and measured with a field H applied at an angle θ to the saturation field. The measured quantities are the remanent magnetization and the microwave hysteresis including minor loops. Especially the microwave absorption curves allow direct analysis of the critical field as a function of the orientation angle cursive-theta0 between H and the easy axis. Starting with these data a fit of the calculated to the measured remanence curves yield the distribution. The figure shows the critical field distribution of a ferrite sample with large coercivity. Additionally the calculated and measured resonance fields ares are given. All field strengths are normalized to the anisotropy field, which can also be determined from the microwave measurement.1
