Abstract :
An approach to measure energy losses in Mn-Zn ferrite rings from DC to the maximum frequency f = 6 MHz is presented. An estimate based on the DC hysteresis curve analysis show that Mn-Zn ferrites have a very low value of the magnetocrystalline anisotropy. The ferromagnetic resonance is calculated. A comparison between prediction and experiments is presented.
