part 8

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 are then as follows:


The magnetic susceptibility for any magnetic field can be calculated as δMα/δBα .

α= xyz.
μB– Bohr magneton
gL=gj= Lande factor
kB= 1,38 x 10 -23 J/K (Boltzmann constant)

The analytical solution of this equation for small field has the form:
