Spectral analysis of higher spins (S$>$1/2) kagome systems

ORAL

Abstract

We will present some recent numerical results concerning higher spin kagome systems, with emphasis on S=3/2. We focus on pure systems calculating exact spectra for different cluster sizes and conclude that no magnetic long range order is found. We complete the analysis by describing some features of such systems doped with non-magnetic impurities.
