Magnetization reversal in ferrite magnets

Journal of Magnetism and Magnetic Materials, 1989
Abstract The effect of particle size on the magnetization reversal in ferrite magnets has been examined by correlating the hard magnetic properties with the microstructure. Initial magnetization curves, field and temperature dependence of coercivity and the remanence curves were obtained and compared with the predictions of theoretical models.

Radially oriented ferrite magnets

IEEE Transactions on Magnetics, 1979
A new manufacturing method, magnetic-field-free-process, to obtain radially oriented ferrite magnets was developed, utilizing the shape anisotropy of the particles of strontium magnetoplumbite, with the following properties : Br = 365mT, bHc = 225kA/m, iHc = 240kA/m, (BH)max = 24kJ/m3, density = 4950 kg/m3, flexural strength = 167MPa.

The magnetization process in ferrites

Physica, 1951
Abstract The initial magnetization curve of ferrites has been measured as a function of frequency up to 2 Mc/s. It has been found that the magnetization of sintered ceramic ferrites with a high permeability is brought about by at least two processes, one of which, in the frequency range covered, is independent of frequency and determines the initial ...
