From the abstract of the paper you cited in your last mail I gather that this an alloy. So I suspect that there is some cite disorder with Co as well as Ga occupying the lattice sites randomly? In that case Co would have a number of different configurations, due to the random distribution, tha

Dear Prof. Pieper, the answers are as follows, *I understand that this is an alloy? If yes, what kind of supercell do you use to model the system?* I do not used any supercell configuration. The case.struct file contains the two atoms as given below. *Are these t2g and eg symmetries actually pr

Not really a comment, just a few questions one might consider (I probably would, but I am half an expert at best): I understand that this is an alloy? If yes, what kind of supercell do you use to model the system? Are these t2g and eg symmetries actually present in all possible configuration

Dear Prof. Lyudmila Dobysheva Thanks for your reply. There was a old paper on this alloy, which show similar kind of results, ie. deep pseudo gap with finite states at Ef. please see the link below http://iopscience.iop.org/article/10.1088/0305-4608/12/2/009/meta In this article they discussed t

Dear Wien2k users, I want to explain the negative temperature co-efficient of Co50Ga50 alloy using DFT. For this, I have run the SCF calculation using experimental XRD parameters with simple spin polarized case. Although, I have seen a sharp fall of DOS around the Ef in total DOS, there have been
