Magnetic Moment and influence of the external magnetic field

An external magnetic field splits the degenerate CEF levels, changes their energy and mixes wave functions of different states. The Cartesian components of the magnetization M (the sum of the single ion magnetic moments m) are then as follows:

where:
α= xyz.
μB– Bohr magneton
gJ= Lande factor
kB= 1,38 · 10 -23 J/K (Boltzmann constant)
