Dear all , I'm working on magnetic semiconductor: it is a half metal : a semiconductor for spin up and a metal for spin down.
When I calculate the optical properties , I do it for spin up ( a semiconducting aspect ) and for spin down ( metallic aspect) , then I addjoint the two spin up-dn *My question is:* The calculation steps are the same for spin up and down? there is no difference between them . I mean : in the case of spin down when the compound is a metal, I introduce the intraband transitions even if the compound is a semi metal?? Waiting your reply and thanks in advance Best Regards Imen
