Instrumentation and methods for low temperature measurements in high magnetic fields
Abstract
Most of the difficulties associated with the accurate measurement of low temperature in the presence of an intense magnetic field are caused by the direct effect of the field on the thermometric properties of almost all the commonly used sensors. A comparison of field-dependent errors as a function of the temperature is presented for several materials and instruments: carbon, carbon-glass, germanium, the platinum resistance thermometers, thermistors, Si and GaAs diodes, thermocouples, capacitance thermometers, and other devices. Magnetic field measurement is also examined with attention to commercially available InAs, InSb, and GaAs Hall effect probes.
