Abstract
The recently discovered pyrochlore superconductor, Cd2Re2O7, was subjected to μSR studies of the superconducting state. Zero-field measurements indicate no significant magnetism in this superconductor, suggesting that magnetic frustration does not play a direct role in the superconductivity. Transeverse field measurements show that Cd2Re2O7 is a type-II superconductor with a fully gapped Fermi surface and a zero temperature penetration depth of ∼7500 Å.
