| Abstract: | All-optical heat transport imaging on the spin-ladder compound Ca9La5Cu24O41 is presented. A ‘time-of-flight’ principle is discussed along with its experimental verification which can be used to measure the bulk thermal diffusion constant. The results of the thermal imaging experiments clearly demonstrate anisotropic magnon heat transport. |
