Abstract
Measurements of electrical resistance below 1° K. are described, including experiments to estimate the thermal contact resistance between the paramagnetic salt and gold wires which were subsequently used as secondary thermometers. The resistance of a dilute copper alloy, a lithium–magnesium alloy, and a sodium specimen was measured. No change was found in the resistance of sodium which might be correlated with the specific heat anomaly previously reported by Rayne. The resistance below the minimum in the gold and copper specimens showed a marked contrast in behavior below 1° K. No minimum was found in the resistance of the lithium–magnesium alloy.
