Thermometric characteristics of carbon fibres (original) (raw)

Sensors and Actuators A: Physical, 1993

Abstract

ABSTRACT The thermometric characteristics of carbon fibres obtained by the carbonization of viscose have been studied in the wide low-temperature range 300-0.3 K. It is shown that their resistance versus temperature dependences can be described by the simple formulae R approximately 1gT and 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 studied are very suitable for the fabrication of microminiature low-temperature sensors.
