Magnetic materials FIRST4MAGNETS

Magnetic materials are categorised as magnetically hard, or magnetically soft materials. Magnetically soft materials are easily magnetised but the induced magnetism is usually temporary. For example, if you rub a permanent magnet along a nail, or a screwdriver,

Magnetite an overview ScienceDirect Topics

Magnetite ores often contain sulfide minerals including pyrrhotite and pyrite. Most sulfide minerals are nonmagnetic and can be rejected by magnetic separation. Monoclinic pyrrhotite, however, in contrast to hexagonal pyrrhotite, is magnetic and is recovered in magnetic concentrates.

Magnetic properties of rocks and minerals

2015-10-24  In magnetic materials, there is a small window of grain sizes (near 20 nm in magnetite) which will be magneti- cally unstable (superparamagnetic) at 470 Hi, but stable (single-domain) at 4700 Hi. Over relatively long"observa- tion times" at 470 Hi, such a grain will appear to be

Chromiteen: A New 2D Oxide Magnetic Material from

Magnetic measurements over a large temperature range of 4 K ≤ T ≤ 300 K confirm ferromagnetic/superparamagnetic order with nearly 40 times higher magnetic moment saturation in chromiteen compared to chromite. The results reveal that 2D chromiteen causes a change in the magnetic behavior with respect to chromite which could be ascribed to the increase in the lattice strain

Magnetic Materials Article about Magnetic Materials

The materials that are most important to magnetic technology are ferromagnetic and ferrimagnetic materials. Their response to a field H is to create an internal contribution to the magnetic induction B proportional to H, expressed as B = μ H, where μ, the permeability, varies with H for ferromagnetic materials.
