Abstract

We have studied the AC susceptibility of Sr₂RuO₄. We detected a peculiar feature near H_c2 for H_dc∥ab-plane, which is correlated with the in-plane H_c2 anisotropy. Both this feature and the magnitude of H_c2 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 H_c2.
