Title: Investigation of the Heisenberg Model on the Basis of the Real Spin‐Wave Theory
Abstract: Abstract The operator formalism of real spin‐waves is introduced. Applying this formalism to the Heisenberg model and making use of a new method of calculation, the energies of the real spin‐waves are renormalized taking into account their interactions. The formula derived for the magnetization in this way leads to better results than those derived by Tyablikov [5], Tahir‐Kheli and ter Haar [6], and in an another approximation by Callen [8].
