Dear all, I was wondering that what the correct units of Stoner parameter (*I*) and DOS(*E*_F) (density of state at Fermi level) used in the Stoner criteria of magnetism (*I**DOS(*E*_F) > 1) is? Does DOS(*E*_F) should have a unit of (atom/energy) or (atom/volume/energy) ... and then similar change for the unit of *I*? Different defined units for them in different literatures cause confusion (for me), or for example when Coulomb repulsion (*U*) is used instead of *I,* the Stoner criteria change to *U**D*(E_*F*) > *(1/v) where v is the unit cell volume*.* Or for instance inspection of the formulas of 14--27 of below reference [1] convinces me that the unit of volume is missing somewhere.
[1]. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.92.9357&rep=rep1&type=pdf In my specific case I consider an simple FCC Ni, and then in non-magnetic phase I calculated the DOS(*E*_F) for one of the Ni atoms such that the integration of the corresponding DOS curve until the Fermi level gives around 10 electron. Thanks for you help. Regards, Alex
