説明
The localized spin wave associated with two different impurities in an insulating b. c. c. antiferromagnet is investigated within the linear spin wave theory. The four cases with regard to the relative position of two impurities which include the case of nearest neighbor positions are considered. The energy of localized spin wave is calculated for the various values of exchange integrals and the magnitude of impurity spin. It may be concluded that some of the localized spin wave modes of the first impurity are not affected even if the second impurity is on the vicinity of the first impurity. When the same two impurities are on the same sublattice the larger interferential effect on the localized spin wave energy is induced than on the different sublattice. The dependence of the localized spin wave energy on the distance between two impurities is discussed briefly.
