Applications Of Ferrite Magnet
, 2017 This work explained in details the Ferrite magnet form the structure, and the properties. It is found that it's consisting of non metallic material such as ceramic, and it is a compound of iron oxide with other different oxides. Also the applications of the two types soft/hard were presented.

Recent Improvements of Ferrite Magnets [PDF]
Le Journal de Physique IV, 1997 This paper overviews recent improvements in the properties of ferrite magnets from two viewpoints. First, new processes for submicron-sized particles, for high orientation and for high density were studied in detail. As a result, high performance Sr-ferrite magnets with Br=0.44T (4.4kG) and HcJ=320kA/m (4.0kOe) were developed.
