Thanks again Mr Juan Manuel for the rich information
Would you tell me to what extent this information is just:
*The character of the unit cell distortion is determined by the orientation
of the easy magnetization direction (EMD) of the compounds for binary RCo2

Thanks again Pr Staphan for the procedure and the article. Unfortunately I
have no idea about the Spin Density Wave and I have to learn more about it.

In order to know the symmetry of a structure you do not have to look at the
unit cell, but to the symmetry group of the structure. You can have a triclinic
structure with a cubic unit cell. Just look at the symmetry group that is
indicated in the database, and you will see that its point-group i
Now , I understand the origins of the tetragonal and the orthorombic
distortions for the cubic structure of Chromium Cr.
I know how to add the spin-orbit coupling in the wien2k code to get the
tertragonal structure , but I don't know how to take the spin-density wave
in account .

Thanks Mr Khan Manuel for your contribution to enrich the subject of
geometrical frustration and magnetism .
After reading your contribution, I made the following remarks:
* you have said:In the case of NiO the magnetic order reduces the symmetry
to monoclinic, but what we know all is that the ma
In general, any magnetic ordering breaks the symmetry of the system, and
structural distortions compatible with the new symmetry can happen due
to magneto-structural coupling. Often this coupling is too weak to be
detected, but in other cases like NiO is strong enough.
And this is indeed what ha
Thanks again and I have read that the lifting of the Geometrical
Frustration lead to Ferrimagnetism.
