[Wien] how to define magnetic moments in directions other than Z-axis

[Rocquefelte]

It corresponds to a non-collinear magnetic situation.
You should use WIENNCM if you want to properly describe this magnetic 
arrangement.
However, in a first step did you simply tried to calculate the energy of 
the AFM structure without taking into account the orientation in space 
of the atomic magnetic moments?
It will give you a first idea (in a collinear way).
