✦ Synopsis
A joint experimental set-up has been constructed for simultaneous low temperature measurements of thermal conductivity, k, of two solid samples and thermal conductance, R~I, at a solid/solid boundary using the steady state method. The thermal measurements presented here were carried out in the temperature range 10-260 K. A discussion of the peculiarities of the thermal conductivity behaviour of YBCO superconducting samples during the cooling cycle has been presented. Initial thermal boundary conductance measurements at the high temperature superconductor/solid (YBCO/ruby) boundary have been performed.
