[Pw_forum] pwscf: energy convergence of noncollinear with spin-orbit calculations

[German Samolyuk]

Dear qe users,

I'm trying to calculate total energy of artificial FCC PtFe compound
with magnetic moment (MM) along z- and x-directionsi (MAE).

In order to supress oscillation of moment direction I used for MM||z calculation
input instructions

 constrained_magnetization = 'total direction' ,
   fixed_magnetization(1) = 0.0,
   fixed_magnetization(2) = 0.0,
   fixed_magnetization(3) = 1.0,

However I can not reach total energy convergence and it looks like I
still have direction oscillation of MM.

What can be done to resolve this problem?

Thank you in advance.

The complete input file for MM||z is and energy accuracy output file
are attached.
