Fixing magnetic moment on each atom in a noncollinear magnetic calculation

1)Is it possible to fix the magnetic moment on each atom in a non-collinear calculation? If yes, what are the tags required for that ?
2) Is it possible to simulate magnetic spiral with VASP ?

1) You can constrain the direction on each respective atom by using a penalty function. Please have a look at this previous thread

for the required tags. However, the value of the magnetic moment for a specific atom cannot be fixed.
2) For simulating spin spirals, please have a look at

Hope this helps
