Formulation of master equation approach involving spin–phonon coupling: Toward an understanding of spin dynamics in magnetic dendrimers

Abstract

A master equation approach involving the effect of the interaction between spins and phonons is formulated in the Markov approximation in order to perform a dynamics for a spin aggregate which have the novel fractal architectures. Such a dynamics is important for elucidating the relation between the dynamical features and the architectures of spin aggregates.
