Spin correlations in disordered spin chain with itinerant electrons — •Andreas Rothe and Alexander Chudnovskiy — Universität Hamburg Jungiusstrsse 9 20355 Hamburg

We investigate spin-spin correlations mediated by itinerant electrons. We calculate the localization length in a special model of a disordered Ising spin chain. We treat this model by means of real space renormalization group (RG). Further we analyse the frequency dependence of the spin-spin correlation function.
