Domain structure of polycrystalline MnZn ferrites

Nanoferrites of nickel doped with cobalt: Influence of Co2+ on the structural and magnetic properties

“…A means of controlling the onset of this stage is to control the heating atmosphere and temperature. [23,24] The FeO and (FeCo) stages indicate the volatilization of metals resulting in compositional shifts favoring the precipitation of secondary phases [25][26][27].…”

Modelling magnetic properties of MnZn ferrites with the modified Jiles–Atherton description

“…The domain structure of MnZn ferrites is affected by material properties such as saturation magnetization, magnetocrystalline anisotropy, grain size and distribution of defects [13,14]. The J-A macroscopic model considers hysteresis as the result of energy dissipation during domain wall translation through these defects, referred to as pinning sites [10].…”

A new Mn–Zn ferrite for high-speed data transmission applications in telecommunication networks

“…Since the magnetization mechanism at low-flux levels proceeds through domain wall movements [3], the B-H non-linearity can be explained by the fact that pores, impurity ions or other inclusions inside the material act as domain wall pinning points, causing irreversible movements of the domain walls. Quantitatively, the reversibility of the domain wall movement is expressed by the so-called hysteresis material constant Z B , which is described by…”
