This property is demonstrated to be a purely quantum mechanical effect by the Bohr-van Leeuwen theorem, and it is possessed by definition by Heusler alloys.
This phenomenon arises only in materials with a very strong characteristic exchange interaction. This property is demonstrated to be a purely quantum mechanical effect by the Bohr-van Leeuwen theorem, and it is possessed by definition by Heusler alloys. Early work on this property was performed by Aleksandr (*) Stoletov. Materials with this property always contain aligned regions called Weiss domains. For 10 points, name this phenomenon present at room temperature in nickel and cobalt, named for its most prominent possessor, iron, a form of magnetism.
