A temperature lower than the Curie temperature, but at which the opposing magnetic moments are equal (resulting in a net magnetic moment of zero) is called a magnetization compensation point. This compensation point is observed easily in garnets and rare-earth–transition-metal alloys (RE-TM). See more A ferrimagnetic material is a material that has populations of atoms with opposing magnetic moments, as in antiferromagnetism, but these moments are unequal in magnitude so a spontaneous magnetization See more There are various ways to describe ferrimagnets, the simplest of which is with mean-field theory. In mean-field theory the field acting on the … See more When ferrimagnets are exposed to an external magnetic field, they display what is called magnetic hysteresis, where magnetic behavior … See more Until the twentieth century, all naturally occurring magnetic substances were called ferromagnets. In 1936, Louis Néel published a paper proposing the existence of a new form of … See more Ferrimagnetism has the same physical origins as ferromagnetism and antiferromagnetism. In ferrimagnetic materials the magnetization is also caused by a combination of … See more Unlike ferromagnetism, the shapes of the magnetization curves of ferrimagnetism can take many different shapes depending on the strength of … See more Ferrimagnetic materials have high resistivity and have anisotropic properties. The anisotropy is actually induced by an external applied field. When this applied field aligns with the … See more WebAug 2, 2024 · Figure 1b shows the temperature dependence of MS of Pt/Co x Gd 1-x /Ta for x = 77 % and 73 %. The local minimum of MS ( T) indicates the magnetic compensation temperature ( TM) at which the magnetic moments of the two antiferromagnetically coupled sublattices cancel each other out.
