Orbital magnetization in periodic solids

The orbital magnetization in periodic solids has been nicely described by the so-called modern theory of magnetization [1,2,3,4]. $$\tag{1} \mathcal{M}_{orb} = -\frac{1}{2} \Im \sum_{n,\mathbf{k}} f_{...

Is it possible to calculate/estimate the value of the J parameter to be used in the Heisengerg/Ising hamiltonians?

Studying magnetic systems, two frequently used approximations are the Heisenberg and Ising models (a discussion about these approximations can be read here): \begin{equation} \tag{Heisenberg} \hat{H}...

Is it possible to calculate the variation of magnetization M(T) for a diluted magnetic semiconductor?

Please if you can help me with some resources and tutorials. Is there any simulation program (for example a DFT package) to determine the variation of magnetization M(T) for diluted magnetic ...
