[Wien] The magnetic structure for zinc blende non magnetic structure

Dear Delamora

It's up to now that I start to work with the magnetic structure of the zinc
blende one.


- The zinc blende structure for NiS has not been studied before and I am
studing the possibility of its existence.

- In the literature, I found that the magnetic ground phase of the zinc
blende is of type III unlike the one of the NaCl which is of type II.

- I have tried to construct the magnetic structure of the zinc blende
structure according to this link and I want to know if I am true or not.

My procedure is as follows:
