Summary

A THIN-FILM PLATINUM RESISTANCE THERMOMETER, WHICH IS AVAILABLE COMMERCIALLY, HAS USEFUL CHARACTERISTICS FOR THERMOMETRY IN THE RANGE OF 20 TO 300 K AND IN HIGH MAGNETIC FIELDS UP TO 5 T. THE Z FUNCTION-TABLE OF THIS PLATINUM RESISTANCE THERMOMETER WAS OBTAINED EXPERIMENTALLY. IT WAS CONFIRMED THAT THIS THERMOMETER WOULD BE USEFUL WITHIN A PRECISION OF + OR -0.1 K. THIS CONFIRMATION WAS ACHIEVED BY USING A TWO-POINT CALIBRATION METHOD WITH THE Z FUNCTION. ITS MAGNETORESISTANCE AT 30 K IS ABOUT 1.5% FOR A MAGNETIC FIELD OF 5 T, WHOSE VALUE IS ONE ORDER OF MAGNITUDE SMALLER THAN THAT OF A STANDARD TYPE.
