Abstract

We have studied the AC susceptibility of Sr2RuO4. We detected a peculiar feature near Hc2 for Hdc∥ab-plane, which is correlated with the in-plane Hc2 anisotropy. Both this feature and the magnitude of Hc2 anisotropy are severely suppressed with the field misalignment of less than 1°. This fact supports that a new superconducting state with a line-node gap exists at higher fields near Hc2.
