Spin and orbital momenta of the magnetic ion in solid

Our calculations, allows to calculate spin and orbit magnetic momenta.

It allows to estimate the spin and orbit magnetic momenta even for |L,S, J,Jz> representation:

μB– Bohr magneton
ge=2.002324– Lande factor for spin

Computable properties:

• Entropy S(T)
• Specific heat Cmol(T)
• Magnetic moment and influence of the external magnetic field for it m(B,T)
• Magnetic susceptibility along different crystal directions χi(T)
• Visibility of the energy levels in spectroscopy <Γi|J_|Γj>, <Γi|J+|Γj> , <Γi|JZ|Γj>
• Spin and orbital momenta of the magnetic ion in solid <Γi|L|Γi>, <Γi|S|Γi>
