Webb22 dec. 2024 · The modern semiclassical theory of a Bloch electron in a magnetic field encompasses the orbital magnetization and geometric phase. Beyond this semiclassical theory lies the quantum description of field-induced tunneling between semiclassical orbits, known as magnetic breakdown. Here, we synthesize t … WebbIn parallel to atoms and molecules, the magnetization in solids has two distinct contributions: the spin magnetization and the orbital magnetization. However, while the first can be computed easily, the latter has eluded exact calculation due to the lack of an appropriate theory. sigalagala technical training institute

Theory of orbital magnetization in disordered systems

WebbThis and later experiments led to the notion that the magnetization of a permanent magnet is somehow due to pemanent currents of electrons. Biot, Savart, and Amp`ere established the relationship of the magnetic induction and the current that generates it. As we know, Maxwell essentially completed the classical theory of electromagnetism. WebbModern theory of orbital magnetization Theory started in 2005, and is still work in progress. Only model-Hamiltonian results published so far.
