Relaxation dynamics of disordered Ising model. Two-site cluster approximation

Condensed Matter 2007-05-23 v1

Abstract

Spin relaxation in a site-disordered Ising model within master equation approach is studied. The q,ω\vec{q},\omega-dependent susceptibility of the model is calculated and investigated. Effects described by the two-site cluster approximation and lost by the mean field approximation are discussed. Comparison of obtained results with dielectric measurements in Cs(H1xDx)2PO4Cs(H_{1-x}D_x)_2PO_4 is presented.
