Double-exchange model for bilayered manganites
Source abstract
Abstract
Abstract We discuss the double-exchange model for bilayered manganites, taking into account the effects of two-fold degeneracy of the e g levels. The obtained phase diagram successfully explains the sequence of ferro- → canted → A-type antiferromagnetic states, observed with the increase of the hole concentration. The direction of the spin magnetization, obtained from the analysis of the magnetocrystalline anisotropy energy, is expected to be parallel to the plane of the layer.
