ferrimagnetic material

Ferrimagnetic materials are also used to produce optical isolators and circulators.

A ferrimagnetic material is similar to a ferromagnet but has two different types of atoms with opposing magnetic moments.

The difference between ferro- and ferrimagnetic materials is related to their microscopic structure, as explained in Magnetism.

This is a spontaneous magnetism which is a property of ferromagnetic and ferrimagnetic materials.

Ferrimagnetic materials have high resistivity and have anisotropic properties.

The tensor notation needs to be used because ferrimagnetic materials become anisotropic in the presence of magnetizing field.

The ordering of magnetic moments in ferromagnetic, antiferromagnetic, and ferrimagnetic materials decreases with increasing temperature.

Normally, any ferromagnetic or ferrimagnetic material undergoes a transition to a paramagnetic state above its Curie temperature.

All other domains are characterized by the presence of ferrimagnetic material, most likely magnetite, which has a sufficiently high susceptibility to produce measurable anomalies.

Ferrite is a ceramic ferrimagnetic material that is nonconductive, so eddy currents cannot flow within it.

Saturation is a characteristic of ferromagnetic and ferrimagnetic materials, such as iron, nickel, cobalt and their alloys.

Ferrimagnetic materials are magnetic in the absence of an applied magnetic field and are made up of two different ions.

Ferromagnetic and ferrimagnetic materials are the ones normally thought of as magnetic; they are attracted to a magnet strongly enough that the attraction can be felt.

Ferrimagnetic materials, which include ferrites and the oldest magnetic materials magnetite and lodestone, are similar to but weaker than ferromagnetics.

Ferromagnetic-core or iron-core inductors use a magnetic core made of a ferromagnetic or ferrimagnetic material such as iron or ferrite to increase the inductance.

Ferrimagnetic materials are like ferromagnets in that they hold a spontaneous magnetization below the Curie temperature, and show no magnetic order (are paramagnetic) above this temperature.

Magnetic domain structure is responsible for the magnetic behavior of ferromagnetic materials like iron, nickel, cobalt and their alloys, and ferrimagnetic materials like ferrite.

Ferromagnetic materials and the closely related ferrimagnetic materials and antiferromagnetic materials can have a magnetization independent of an applied B-field with a complex relationship between the two fields.

A nonzero orbital magnetization requires broken time-reversal symmetry, which can occur spontaneously in ferromagnetic and ferrimagnetic materials, or can be induced in a non-magnetic material by an applied magnetic field.

The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.

Ferromagnetic and ferrimagnetic materials become disordered and lose their magnetization beyond the Curie temperature and antiferromagnetic materials lose their magnetization beyond the Néel temperature .

This high coercivity interval has no obvious correlation to climate change, but appears to be related to the increased preservation of ultrafine single domain ferrimagnetic material due to a lack of reduction diagenesis within this interval.

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.

It is a ferrimagnetic material with a Curie temperature of 560 K. YIG may also be known as Yttrium ferrite garnet, or as Iron yttrium oxide or Yttrium iron oxide, the latter two names usually associated with powdered forms.

Some ferrimagnetic materials are YIG (yttrium iron garnet), cubic ferrites composed of iron oxides and other elements such as aluminum, cobalt, nickel, manganese and zinc, hexagonal ferrites such as PbFeO and BaFeO, and pyrrhotite, FeS.
