Re: [Wien] Change of structure symmetry

Thank you, No, I do not think that it is crystallographically wrong, it is just the way that sgroup chooses to put the lines This way . . . / / . . . connecting diagonally or this way . . . | | . . . connecting vertically both are correct

Re: [Wien] Change of structure symmetry

Thank you, I have encountered this problem before and I was able to use the orthorhombic cell, but in this case the task was much harder, and if sgroup had this ability to choose the most "compact" cell it would be nice. For example a square cell is correct (in 2D), but if one puts lines at 45

Re: [Wien] Change of structure symmetry

It is not always mandatory to take the changes suggested by sgroup into account. (This is the reason why it is not made automatically). For low symmetry structures (monoclinic) there are many possible settings and even the construction of the unit cell is not unique, but arbitrary equivalent

Re: [Wien] Change of structure symmetry

I agree with you -- it would be nice if 90 was kept although formally I believe it is crystallographically wrong. I have never tried to tweak the code as it is in C which I don't like much. Maybe someone who likes C can look. --- Professor Laurence Marks "Research is to see what everybody

Re: [Wien] Which notation for the spin direction in hexagonal structure

Hello again I have resolved the problem. Now I ovserved that as in the case of NiO , the spin-orbit coupling doesn't improve the gap for my compound. My question is: Which quantities are influenced by the spin-orbit coupling? Best regards -- Mr: A.Reggad Laboratoire de Génie Physique
