Spin glass models can present these amorphous types of magnetism. [2] Due to random frustration, amorphous magnets possess many nearly degenerate ground states. [1] The terms for the amorphous magnetic phases were coined by Michael Coey in 1970s. [2] [3] [4] The Greek root spero/speri (Greek: διασπειρω, romanized: diaspeiro) means 'to ...
An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline, and have a glass-like structure.
The default definition of magnetic remanence is the magnetization remaining in zero field after a large magnetic field is applied (enough to achieve saturation). [1] The effect of a magnetic hysteresis loop is measured using instruments such as a vibrating sample magnetometer ; and the zero-field intercept is a measure of the remanence.
Hematine ring. Hematine (also magnetic hematite, hemalyke or hemalike) is an artificial magnetic material. [1] Hematine is widely used in jewelry. [citation needed]Although it is claimed by many that it is made from ground hematite or iron oxide mixed with a resin, analysis (of one object) has demonstrated it to be an entirely artificial compound, a barium-strontium ferrite.
Jewellery design is the art or profession of designing and creating jewellery. It is one of civilization's earliest forms of decoration , dating back at least 7,000 years to the oldest-known human societies in Indus Valley Civilization , Mesopotamia , and Egypt .
Another class of design is the magnetic mangle (B), proposed by Coey and Cugat, [20] [21] in which uniformly magnetized rods are arranged such that their magnetization matches that of a Halbach cylinder, as shown for a 6-rod design. This design greatly increases access to the region of uniform field, at the expense of the volume of uniform ...

When writing, the magnetic medium is heated locally by a laser, which induces a rapid decrease of coercive field. Then, a small magnetic field can be used to switch the magnetisation. The reading process is based on magneto-optical Kerr effect. The magnetic medium are typically amorphous R-Fe-Co thin film (R being a rare earth element).
