Wide Range Thin-FIlm Ceramic Metal-Alloy Thermometers with Low Magnetoresistance

Abstract

Many thermal measurements in high magnetic fields require thermometers that are sensitive over a wide temperature range, are low mass, have a rapid thermal response, and have a minimal, easily correctable magnetoresistance. Here we report the development of a new granular-metal oxide ceramic composite (cermet) for this purpose formed by co-sputtering of the metallic alloy nichrome Ni${}_{0.8}$Cr${}_{0.2}$ and the insulator silcon dioxide SiO${}_2$. The resulting thin films are sensitive enough to be used from room temperature down to below 100 mK in magnetic fields up to at least 35 tesla.
