Measurements of the resistance and the magnetoresistance of a new ceramic thin-film temperature sensor (Cernox-1080, Lake Shore Cryotronics Inc.) are reported for magnetic fields up to 13 T in the temperature range 4.2 to 300 K. The zero-field resistance changes monotonically over more than three orders of magnitude with a negative temperature coefficient. The magnetoresistance is small at temperatures above 10 K and exhibits partially compensating positive and negative components. The magnetic-field induced temperature reading error at 13 T is about 2% at 4.2 K and less than 0.3% at 10 K and above. In the temperature range 80 to 300 K, the magnetoresistance can be approximated by a fourth-order polynomial, allowing for an estimation and correction of the apparent temperature reading error of the Cernox thermometer in high magnetic fields.
