Abstract

We carried out measurements of thermal conductivity in a crystal quartz substrate (900 $\mu $m thick) at temperatures of 1.4 K by using a pumped $^{4}$He cryostat. We applied a varied input power from 0.1 up to 1 mW to the heater placed at the end of the substrate, and we observed that the measured data give a temperature dependence of $k= 0.12 T^{2.7}$ W/cm$\cdot$K.
