BISMUTH MAGNETORESISTIVE THERMOMETRY FOR TRANSIENT TEMPERATURE MEASUREMENTS IN LIQUID HELIUM.

Author(s) : BRODIE L. C.

Type of article: Article

Summary

A SINGLE CRYSTAL OF BISMUTH CAN BE USED EFFECTIVELY AS A THERMOMETER FOR TRANSIENT TEMPERATURE MEASUREMENTS AT LOW TEMPERATURES. THE THERMOMETRIC PROPERTY WHICH IS EXPLOITED IS THE STRONGLY TEMPERATURE DEPENDENT MAGNETORESISTANCE EXHIBITED BY THESE CRYSTALS AT LIQUID HELIUM TEMPERATURES. THE BISMUTH THERMOMETER IS CHARACTERIZED BY A FAST THERMAL RESPONSE, GOOD SENSITIVITY, LOW KAPITZA RESISTANCE, AND EASE OF ELECTRICAL RESISTANCE ADJUSTMENT, AND IT IS PARTICULARLY WELL SUITED TO THE SITUATION IN WHICH THE THERMOMETER IS ITSELF USED AS A HEATER.
