Ferrites

Journal of the American Ceramic Society, 1958
Ferrites are magnetic iron oxide compounds having, in general, the spinel structure. Because of their high resistivity as compared to magnetic alloys, they are used wherever high frequencies are involved. During the last 15 years several distinct classes of ferrites have been developed, different with respect to chemical constitution as well as ...

Fine-Grained Ferrites. I. Nickel Ferrite

Journal of Applied Physics, 1961
A process has been developed for preparing dense nickel ferrite bodies composed of grains small enough to remain single domain. The magnetic and crystallographic properties of these bodies have been determined. This was accomplished by combining two techniques, flame-spraying and hot-pressing, and investigating the effect of varying the parameters in ...

Ferrite microwave detector

IRE International Convention Record, 1958
In treating the behavior of the magnetic moments of unbalanced electron spins in ferromagnetic materials under the action of an rf field, second-order terms in the alternating components are usually neglected. It is shown here that retention of certain second-order terms for one component of the magnetization predicts the possibility of using ferrites ...
