Note that L z and S z are no longer conserved quantities. Substituting in this equation expressions for the magnetic moment and the magnetic field, one gets.
Views Read Edit View history. CEF interactions and magnetic interactions resemble, somehow, Stark and Zeeman effect known from atomic physics.
Here we make the central field approximationthat is, that the electrostatic potential is spherically symmetric, so is only a function of radius. Please help improve it to make it understandable to non-expertswithout removing the technical details. The SL and J of the ground multiplet are determined by Hund’s rules.
Spin–orbit interaction – Wikipedia
The interaction between the magnetic field created by the electron and the magnetic moment of the nucleus is a slighter correction to the energy levels known as the hyperfine structure. The spin—orbit potential consists of two parts. This approximation is exact for hydrogen and hydrogen-like systems. Now we have to take into account Thomas precession correction for the electron’s curved trajectory.
Electron Paramagnetic Resonance of Transition Ions. While in ESR the coupling is obtained via the magnetic part of the EM wave with the electron magnetic moment, the ESDR is the coupling of the electric part with the spin and motion of the electrons.
T 2 gA 2 gwhich are partially split by spin—orbit interactions and if occur lower-symmetry CEF interactions. This mechanism has been proposed for controlling the spin of electrons in quantum dots and other mesoscopic systems. Putting it all together, we get.
The case of strong cubic CEF   for 3 d transition-metal ions interactions form group of levels e. This phenomenon is detectable as a splitting of spectral lineswhich can be thought of as a Zeeman effect product of two relativistic effects: In Llewellyn Thomas relativistically recomputed the doublet separation in the fine structure of the atom.
Elements of this basis have the five quantum numbers: This section may be too technical for most readers to understand.
The addition spn these three corrections is known as the fine structure. Although in the rest frame of the nucleus, there is no magnetic field acting on the electron, there is one in the rest frame of the electron see classical electromagnetism and special relativity.

Note that the spin-orbit effect is due to the electrostatic field of the electron and not the magnetic field created by its orbit.
This page was last edited on 9 Decemberat The fine spim structure can be directly detected by many different spectroscopic methods, including the inelastic neutron scattering INS experiments.
Retrieved from ” https: A crystalline solid semiconductor, metal etc. From Wikipedia, the free encyclopedia. This technique is based on the equivalent operator theory  defined as the CEF widened by thermodynamic and analytical calculations defined as the supplement of the CEF theory by including thermodynamic and analytical calculations.
Operator methods in ligand field theory. The bands of interest can be then described by various effective models, usually based on some perturbative approach. The Theory of Transition Metal Ions. Now we can say that. For rare-earth ions the spin—orbit interactions are much stronger than the CEF interactions.
