Dear Tomas, at the moment I do not see something being obviously suspicious. Maybe the culprit is some structural phase transition invalidating the experimental structure you compare with. You might get one or two ideas from Stefaan Cottenier's work? Error Estimates for Solid-State

[Wien] large deviation of atomic volume in BiNi compound

Dear Wien2k users, I came across a problem with equilibrium atomic volume of the BiNi compound. The experimental lattice is hexagonal with a = 4.079 Angstroem, c = 5.359 Angstroem (P. Villars, Pearson's Handbook: Crystallographic Data for Intermetallic Phases) However, the equilibrium

Since you ask for ideas and without really looking at the problem: Assuming that the experimental numbers are correct, is this a room temperature structure? The calculations are, of course, ground state zero Kelvin, so things might go south if there is a phase transition somewhere. Considering

Dear Martin and Gerhard,  Thank you for your suggestions. Gerhard, thank you for mentioning this experimental work. Will you please send me the pdf  of the article? I do not have access to it. Regarding Martin's questions:  I tried to include magnetism  of the constituents by performing
