✦ Synopsis

We have measured the resistance and magnetoresistance of commercially produced thick film resistors in the range 80 K-15 mK and in fields up to 20 T. These resistors behave similarly to those produced by another manufacturer and characterized recently by a Japanese group.

Between 2.5 and O. 1 K the resistance of a 1 kf~ resistor can be fit to R = Aexp(B/T 1/4). A 100 kf~ resistor appears to fit a similar expression between 1.6 and 6 K and fits a T-1/2 law from 8 to 80 K. These resistors are very stable upon thermal cycling, have a small magnetoresistance, and should be useful as thermometers over a wide temperature range.
