Abstract


The factors influencing magnon heat conductivity of the hole-doped spin ladders in Sr14-xCaxCu24O41 were analyzed. It was observed that the magnon heat conductivity was strongly affected by magnon-hole scattering. The anomalies of electronic transport was correlated with the drastic temperature and doping dependent changes. The results of the study show that charge ordering of the holes in the ladders lead to a freezing out of magnon-hole scattering processes.
