[Wien] U , J and effective U

[delamora]

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
