Ferrites exhibit ferrimagnetism, which is different from the ferromagnetism seen in metals such as iron, cobalt, and nickel. In ferrites, the magnetic moments of constituent atoms align themselves in different directions.
However, there is a partial cancellation of the magnetic moments which result in the ferrimagnetic property. The broken Cited by: 1. Ferrite cores, composite materials and accessories - order print version PDF download convince yourself of our products.
The book traces the origin of the magnetic effect in ferrites from the level of the simplest particle and then increases the scope to include larger hierarchies. From the desired magnetic properties, the author deduces the physical and chemical material Ferrites book, taking into consideration major chemistry, impurity levels, ceramic.

Ferrites may possess a normal or inverse spin structure. Detailed reviews of the structures and magnetic properties of ferrites have been given by Dormann and Nogues ().
The name spinel is given to those ferrites which have the formula MFe 2 O 4 (where M is a divalent ion) and which have the cubic crystal structure of the mineral spinel. Get this from a library. Ferrites. [Philips Electronics N.V.] -- Leaflet advertising Smit and Wijn's book about ferrites (physical properties of ferromagnetic oxides in relation to their application.").
Nanostructured spinel ferrites have gained a great deal of attention. It comes from the possibility of tuning their magnetic properties by careful manipulation of the synthetic conditions. At the same time, since the nanoparticle (NP) surface is reactive toward many chemical groups, it provides great versatility for further functionalization of the by: 2.
Lithium ferrite (LiFe5O8) is a cubic ferrite, belongs to the group of soft ferrite materials with a square hysteresis loop, with high Curie temperature and magnetization. The spinel structure of LiFe5O8 has two crystalline forms: ordered, β-LiFe5O8 (Fd3m space group) and disordered, α-LiFe5O8 (P/P space group).
It has numerous technological applications in Cited by: 5. J. Smit & H.P.J. Wijn Ferrites Philips Technical Library Acrobat 7 Pdf Mb. Scanned by artmisa using Canon DRC + flatbed option.

Hexagonal ferrites There are a number of ferrites that crystallize in hexagonal structure, and some of them have gained considerable technological importance in recent years.
These ferrites are further sub-classified into M, W, Y, Z and U compounds. All these have different, though related, crystal structures.
Ferrite, a ceramic-like material with magnetic properties that are useful in many types of electronic devices. Ferrites are hard, brittle, iron-containing, and generally gray or black and are polycrystalline—i.e., made up of a large number of small crystals.

Ferrite. A ferrite is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe 2 O 3, rust) blended with small proportions of one or more additional metallic elements, such as barium, manganese, nickel, and zinc.
They are electrically nonconductive, meaning that they are insulators, and ferrimagnetic, meaning they can easily be magnetized or attracted to a magnet. Between andthere was a spate of intense activity to investigate the theory and application of ferrite materials at microwave frequencies, and in the early s a number of textbooks on the microwave applications of ferrites were published, but nothing comprehensive since.
Now this book has been written to consolidate all the investigations of ferrites for. Book Cover. Title: Ferrites.

Authors: C. Author: C. Srivastava. P.J. van der Zaag, in Encyclopedia of Materials: Science and Technology, The net magnetic moment of spinel ferrites is thus determined by the sum of the magnetic moments of the two spins on the B-site minus the moment of the A-site.
