Magnetic Properties of Mn-Zn Power Ferrites


In this paper, Mauricio Esguerra, Ibrahim Ellithy and Rewanth Radhakrishnan investigate the effect of hydrostatic stress on magnetic properties of Mn-Zn power ferrites at varying excitation levels.

A novel testing method was developed to continuously measure the power losses and the magnetic susceptibility in dependence on magnetic excitation at a fixed frequency and room temperature with the Bode 100 vector network analyzer. The magneto-mechanical effect on core losses was simulated with the Hodgdon-Esguerra hysteresis model, showing excellent agreement with tested results, which allows to predict the behavior of ferrite tiles embedded in load-bearing surfaces for Wireless Power Transfer (WPT) applications.
