A SQUID magnetometer, used as a highly sensitive ammeter, has been used to perform standard electroanalytic chemical measurements noninvasively. Specifically, the magnetic fields generated by the net ionic movement in the solution of a driven electro

A 15.7% anisotropy in the superconducting energy gap has been measured by electron tunneling into single crystals of rhenium, using thin carbon films as the tunneling barrier to form Re-C-In sandwiches. The energy-gap behavior vs temperature is BCS-l

Examination of available tunneling data from junctions oriented on single-crystal niobium shows that the observed superconducting energy gap values are grouped nonrandomly in $k$ space. These groupings are consistent with a relationship between ${\en

Low-temperature tunneling studies of high-purity single crystals of niobium indicate the existence of two energy gaps ${\ensuremath{\Delta}}_{s}$ and ${\ensuremath{\Delta}}_{d}$, one for each of the two bands lying at the Fermi level. The value of ${
