ferrite

1. Any of a group of nonmetallic, ceramiclike, usually ferromagnetic compounds of ferric oxide with other oxides, especially such a compound characterized by extremely high electrical resistivity and used in computer memory elements, permanent magnets, and various solid-state devices. Also called ferrate.
2. Iron that has not combined with carbon, occurring commonly in steel, cast iron, and pig iron below 910°C.

A powdered, compressed and sintered magnetic material having high resistivity. The high resistance makes eddy current losses low at high frequencies.

The noun has one meaning:

Meaning #1: a solid solution in which alpha iron is the solvent

Ferrite may refer to:

• Ferrite (iron), iron or iron alloys with a body centred cubic crystal structure.
• Ferrite (magnet) (e.g. Fe₃O₄ or BaFe₁₂O₁₉), ferrimagnetic ceramic materials used in magnetic applications.
• Ferrite beads, components placed on the end of data cables to reduce interference.
• Calcium aluminoferrite, Ca₂(Al,Fe)₂O₅, a mineral found in cements
