WebSep 7, 2024 · In ferromagnetic materials, long range alignments of magnetic moments, called domains, contain magnetic moments that all point in the same direction. However, if a material were to have all of its magnetic moments pointed in the same direction, this would create a very large external magnetic field. This field is not energetically minimizing as ... WebL. Dubrovinsky, N. Dubrovinskaia, in Comprehensive Inorganic Chemistry II (Second Edition), 2013 2.09.6.3 CrO 2. Chromium dioxide is a half-metallic ferromagnet with a very characteristic property: d electrons with spin-up polarization occupy partially filled bands that cross the Fermi level, whereas the Fermi level lies in a gap between the valence and …
WebFeb 20, 2024 · Ferromagnets Only certain materials, such as iron, cobalt, nickel, and gadolinium, exhibit strong magnetic effects. Such materials are called ferromagnetic, after the Latin word for iron, ferrum.
