✦ Synopsis

The thermal conductivity, k, of YBCO superconducting oxides and the thermal conductance, Rb -1, at the YBCO/ruby boundary have been simultaneously measured during a heating cycle using a joint experimental set-up and a steady state method. The measurements were carried out in the temperature range 10 -260 K. Thermal hysteresis of both the thermal conductivity and thermal boundary conductance have been observed within the temperature interval 40 -230 K. Some speculations and substantiations using other methods of measurement are offered in order to explain the observed behaviour of k(T) and Rbl(T).

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 tempe
