Thanks Delamora for your answer and this is not what i am looking for and I
am sorry that I couldn't communicate what I want.
My problem is as follows:
1- I am considering this non magnetic structure (orthorhombic )
* the non-magnetic structure is in this link
https://ibb.co/nt2nFm
* The struct file is:
NiS-MnP
P LATTICE,NONEQUIV.ATOMS: 2 62_Pnma
MODE OF CALC=RELA unit=ang
10.056514 6.692230 10.722761 90.000000 90.000000 90.000000

2- I want to construct the AFM structure of type III as in the following link
https://ibb.co/mqySFm
* I have used the supercell 1x1x1 P to make the four Ni atoms independent
* I have put the atoms (X=0.00500000 Y=0.25000000 Z=0.20000000) and
(X=0.99500000 Y=0.75000000 Z=0.80000000) to *UP*
and the atoms (X=0.50500000 Y=0.25000000 Z=0.30000000) and
(X=0.49500000 Y=0.75000000 Z=0.70000000) to *DOWN*
* I have used the *sgroup*
- I get the following AFM structure
NiS-MnP-afmIII

4 NUMBER OF SYMMETRY OPERATIONS
My question is:
*Is the AFMIII structure or not?*
*NB: What's mysterious is this AFM structure that the space group is
monoclinic and the lattice parameters are orthorhombic.*
*Best regards*
