Summary

RESISTIVITY OF METALLIC SAMPLES IN THE FORM OF FOILS OR WIRES CAN BE MEASURED. THE TEMPERATURE IS CONTROLLED BELOW 4.2 K WITHIN + OR -5 MILLIK BY CONTROLLING HELIUM VAPOUR PRESSURE AND AT HIGHER TEMPERATURES WITHIN + OR -30 MILLIK. THE STANDARD DC FOUR-PROBE TECHNIQUE IS USED FOR MEASURING THE SAMPLE RESISTIVITY.
