Various ferrite cores used to make small transformers and inductors A ferrite AM loopstick antenna in a portable radio, consisting of a wire wound around a ferrite core A variety of small ferrite core inductors and transformers. Ferrites that are used in transformer or electromagnetic cores contain nickel, zinc, and/or manganese [20] compounds ...
Ferrite, a ceramic compound, is one of the most common examples of a ferrimagnetic material. A ferrimagnetic material is a material that has populations of atoms with opposing magnetic moments , as in antiferromagnetism , but these moments are unequal in magnitude, so a spontaneous magnetization remains.

[n 6] Selenium, in particular, is commonly designated as a metalloid in environmental chemistry [n 7] on account of similarities in its aquatic chemistry with that of arsenic and antimony. [n 8] There are fewer references to beryllium, in spite of its periodic table position adjoining the dividing line between metals and nonmetals. Isolated ...
Below 912 °C (1,674 °F), iron has a body-centered cubic (bcc) crystal structure and is known as α-iron or ferrite.It is thermodynamically stable and a fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-Fe discussed below.

Barium ferrite is a highly magnetic material, has a high packing density, [clarification needed] and is a metal oxide. Studies of this material date at least as far back as 1931, [ 3 ] and it has found applications in magnetic card strips, speakers, and magnetic tapes . [ 1 ]
Hexagonal ferrites or hexaferrites are a family of ferrites with hexagonal crystal structure. The most common member is BaFe 12 O 19, also called barium ferrite, BaM, etc. BaM is a strong room-temperature ferrimagnetic material with high anisotropy along the c axis. [1]
Cobalt ferrite is a semi-hard ferrite with the chemical formula of CoFe 2 O 4 (CoO·Fe 2 O 3). The substance can be considered as between soft and hard magnetic material and is usually classified as a semi-hard material.
