[Pw_forum] Workfunction and Magnetism

Dear all,
I have 2 questions I would like to consult:

1.	After calculating surface energy for a slab calculation, can we use PWSCF 
to extract the workfunction of the surface? If so, is it specify somewhere? 
I'm interested in comparing the change in the workfunction between the clean 
surface and the adsorbate-surface.

2.	As I will be working on magnetic systems very soon, I would like to ask how 
to specify it in the run. I understand that some of the parameters like nspin 
will be set to 2 and the starting_magnetization(1) will be needed to be set 
between -1 and 1. So what would the values 1 and -1 mean? I will be working 
specifically on iron sulphide systems.

Many thanks.
