Abstract
We have performed ZF-μSR measurements of Sr2RuO4 and have observed a spontaneous magnetic field below Tc. This observation, combined with other symmetry considerations demonstrates that superconductivity in Sr2RuO4 is of `p-wave' (odd-parity) type. Our transverse field μSR measurements in the mixed state with B = 150 G∥c clearly indicate the presence of a square flux lattice. We have analyzed the field distribution in terms of the penetration depth, coherence length and a Fermi surface anisotropy term and found λ(T = 0) = 1900 angstroms. λ(T→0) is quite flat, consistent with a superconducting gap with no nodes as expected for the Eu(kx±iky) state.
