Antiferromagnetism, type of magnetism in solids such as manganese oxide (MnO) in which adjacent ions that behave as tiny magnets (in this case manganese ions, Mn2+) spontaneously align themselves at relatively low temperatures into opposite, or antiparallel, arrangements throughout the material so This is known as “spontaneous magnetization,” which is a result of parallel orientation of the individual magnetic moments that must be due to interactions between these moments. Ferromagnetic and antiferromagnetic materials are such two types. For Ba 0, a non-zero solution is possible only if Fe3O4? Share. There are three different types of “magnetic ordering,” known as ferromagnetism, antiferromagnetism, and ferrimagnetism. Antiferromagnet Ferrimagnetic ordering Dai/PHYS 342/555 Spring 2012 Chapter 12-1. Ferrimagnetism is exhibited by ferrites and magnetic garnets. In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions. Ferromagnetism, Antiferromagnetism, and Ferrimagnetism. Antiferromagnetism is the presence of magnetic domains that are aligned in opposite directions in magnetic materials.

The second characterization is the sign of the material’s susceptibility, χ, that describes how responsive a material is to the applied magnetic field. 1. First confirmed by Shull at 1949 using neutron scattering. Related to Antiferromagnetism: ferrimagnetism Antiferromagnetism A property possessed by some metals, alloys, and salts of transition elements in which the atomic magnetic moments, at sufficiently low temperatures, form an ordered array which alternates or spirals so as to give no net total moment in zero applied magnetic field. Ferrimagnetism is exhibited by ferrites and magnetic garnets. The present position of our knowledge of antiferromagnetism, including ferrimagnetism, is reviewed, and some very interesting phenomena concerning the magnetic behaviour of certain ferrites and of pyrrhotite are described and explained.
