Hysteresis loop Induction B as function of field strength H for H varying between H min and H max; for ferromagnetic material the B has different values for H going up and down, therefore a plot of the function forms a loop instead of a curve joining two points; for perminvar type materials, the loop is a "rectangle" (Domain Structure of Perminvar Having a Rectangular Hysteresis Loop, Williams ...
Multiferroics are defined as materials that exhibit more than one of the primary ferroic properties in the same phase: [1] ferromagnetism – a magnetisation that is switchable by an applied magnetic field; ferroelectricity – an electric polarisation that is switchable by an applied electric field
Internally, ferromagnetic materials have a structure that is divided into domains, each of which is a region of uniform magnetization.When a magnetic field is applied, the boundaries between the domains shift and the domains rotate; both of these effects cause a change in the material's dimensions.
The manufacturability of the materials depend on the thermal equilibrium solubility of the dopant in the base material. E.g., solubility of many dopants in zinc oxide is high enough to prepare the materials in bulk, while some other materials have so low solubility of dopants that to prepare them with high enough dopant concentration thermal nonequilibrium preparation mechanisms have to be ...
Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial ...
Below the magnetization compensation point, ferrimagnetic material is magnetic. At the compensation point, the magnetic components cancel each other, and the total magnetic moment is zero. Above the Curie temperature, the material loses magnetism. Ferrimagnetism has the same physical origins as ferromagnetism and antiferromagnetism.
A magnetic shape-memory alloy (MSMA) is a type of smart material that can undergo significant and reversible changes in shape in response to a magnetic field. This behavior arises due to a combination of magnetic and shape-memory properties within the alloy, allowing it to produce mechanical motion or force under magnetic actuation.
A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism.Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve): iron (Fe), nickel (Ni), or cobalt (Co).
