minière Ferromagnetism

Ferromagnetism | physics | Britannica

Ferromagnetism, physical phenomenon in which certain electrically uncharged materials strongly attract others. Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe 3 O 4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets.

Ferrimagnetism | physics | Britannica

Ferrimagnetism, type of permanent magnetism that occurs in solids in which the magnetic fields associated with individual atoms spontaneously align themselves, some parallel, or in the same direction (as in ferromagnetism), and others generally antiparallel, or paired off in opposite directions (as in antiferromagnetism).

Ferromagnetism - an overview | ScienceDirect Topics

The internal field in ferromagnetism may be a thousand times greater (χ ≫ 1) than that of diamagnetic and paramagnetic materials. Unfortunately, it is a relatively rare property among the elements, occurring only in the transition metals iron, nickel, and cobalt, and in the lanthanides.

Ferrimagnetism - Wikipedia

In physics, a ferrimagnetic material is one that has populations of atoms with opposing magnetic moments, as in antiferromagnetism; however, in ferrimagnetic materials, the opposing moments are unequal and a spontaneous magnetization remains. This happens when the populations consist of different materials or ions (such as Fe 2+ and Fe 3+).

Antiferromagnetism | physics | Britannica

Antiferromagnetism, type of magnetism in solids such as manganese oxide (MnO) in which adjacent ions that behave as tiny magnets (in this case manganese ions, Mn 2+) spontaneously align themselves at relatively low temperatures into opposite, or antiparallel, arrangements throughout the material so that it exhibits almost no gross external magnetism.

Difference Between Ferromagnetism and Antiferromagnetism ...

Apr 06, 2018· Ferromagnetism is the presence of magnetic domains which are aligned into the same direction in magnetic materials. The most common examples of ferromagnetic materials are metals such as iron, nickel, cobalt and their metal alloys. The magnetic domains of these metals have strong interactions due to the electronic exchange between atoms.
