• Thermometric properties of the recently proposed rhodium-iron (mole fraction 0.5%) wire resistance thermometers with fused-silica coil frames are investigated down to 2.3 K. The thermometers annealed between 800℃ and 900℃ are calibrated down to 2.3 K with an accuracy of 1 mK by a simple method using a reference function and three reference temperatures, 4.2 K, 13.8 K and 24.5 K, which are the most convenient calibration points in this temperature region. The stabilities in thermal cycling between 4.2 K and room temperature and the self-heating effects due to the measuring current are reasonable for the same accuracy.
