Abstract
The thermometric characteristics of carbon fibres obtained by the carb onization of viscose have been studied in the wide low-temperature ran ge 300-0.3 K. It is shown that their resistance versus temperature dep endences can be described by the simple formulae R approximately 1gT a nd R approximately exp(T0/T)n, n < 1, and the magnetoresistance at 4.2 K under magnetic fields of up to 7 T is no more than 4%. The fibres s tudied are very suitable for the fabrication of microminiature low-tem perature sensors.
