[Wien] U , J and effective U

[Fecher, Gerhard]

Please read the review by Anisimov et al. :
J. Phys.: Condens. Matter 9 (1997) 767

or some of his original works
Phys Rev B 43 1991 7570
Phys Rev B 44 1991 943

btw: the Coulomb interaction does not depend on the spin, indeed.

"I think the problem, to be quite honest with you,
is that you have never actually known what the question is."

Betreff: [Wien] U ,  J and effective U

Dear WIEN2k community,

        I have a discussion with my Professor, John B Goodenough, and I would like to share with you.

        Is the U or the effective U (U-J) the same for up and down spin?

        We are working in ruthenates and in some cases they are half metals, so the mobility of the up and down spins is different so the intraatomic correlation should be also different.

        Yours
