PAIR CORRELATIONS IN SUPERCONDUCTING TANTALUM
Journal Article

· Phys. Rev. Letters
Superconducting tantalum was investigated to determine the periodicity of the transition temperature. The transition to the superconducting state was broad, beginning at 4.1 deg K and being complete at approximates 1.5 deg K. Over a small region of temperature between 2.4 and 2.2 deg K the characteristic periodic variations of the resistance due to the variation in the transition temperature could be seen as the magnetic field was varied sinusoidally. Excellent agreement between the observed period and hc/2e is obtained, showing through the factor 2e that the electrons are indeed correlated in pairs in superconducting tantalum. (C.E.S.)
