[Pw_forum] Magnetization

[Giovanni Cantele]

Look through the documentation/tutorials that turn out to be quite helpful to understand basic features of the code.

An example of magnetic calculation is in PW/examples/example01 (see the spin-polarized calculation for nickel).

Also, retrieved for example from http://media.quantum-espresso.org/santa_barbara_2009_07/ <http://media.quantum-espresso.org/santa_barbara_2009_07/> :

http://media.quantum-espresso.org/santa_barbara_2009_07/slides-exercices/MagnCorr.pdf

As you will see, you must use the variables nspin and starting_magnetization to drive the system out of the local, spin-unpolarised minimum.
If your system is magnetic, the output file will show you final values of the total and/or absolute magnetisation different from zero.
