Using the Abrikosov's pseudo-fermion representation of a single spin S and the Larsen's note with pseudefermion energy λ = 0, we describe a procedure which allows calculation of spin-spin interaction as well ts spin-electron (hole) interaction for the case of spin S = 1 by usingstandard methods including the linked cluster theorem of diagrammatic perturbation theory. In particular we derive the multiple-exchange-mediated interaction in the case of S = 1 and predict the possibility of a higher Tc such as 170 K.
Abstract
Using the Abrikosov's pseudo-fermion representation of a single spin S and the Larsen's note with pseudefermion energy λ = 0, we describe a procedure which allows calculation of spin-spin interaction as well ts spin-electron (hole) interaction for the case of spin S = 1 by usingstandard methods including the linked cluster theorem of diagrammatic perturbation theory. In particular we derive the multiple-exchange-mediated interaction in the case of S = 1 and predict the possibility of a higher Tc such as 170 K.
