Theory of orbital magnetization in solids
WebbOrbital magnetization, , refers to the magnetization induced by orbital motion of charged particles, usually electrons, in solids. The term orbital distinguishes it from the contribution of spin degrees of freedom, , to the total magnetization. A Webbthe discoveries, first in solid state and then in the field of molecular magnetism, of 4f ion mononuclear complexes presenting slow relaxation of the magnetization, i.e. with single-molecule magnet (SMM) behaviour. 1,2 In the past decade, the impact of mononuclear SMMs, also known as single-ion

In quantum mechanics, orbital magnetization, Morb, refers to the magnetization induced by orbital motion of charged particles, usually electrons in solids. The term "orbital" distinguishes it from the contribution of spin degrees of freedom, Mspin, to the total magnetization. A nonzero orbital magnetization requires broken time-reversal symmetry, which can occur spontaneously in ferromagnetic and ferrimagnetic materials, or can be induced in a non-magnetic material by an ap… WebbThonhauser_2011_Theory of orbital magnetization in solids R.
