Anomalous Resistance of Pure Gallium Near 1.7°K

Abstract
The electrical resistivity of large single crystals of 99.9999+% gallium has been found to exhibit anomalous behavior near 1.7°K. The temperature at which the anomaly occurs decreases extremely rapidly with increasing magnetic field. Measurements were made with currents as small as 0.005 A, using a potentiometric system with 1015-V sensitivity.
