Abstract

Nature of the pairing and vortex states are studied in Sr₂RuO₄ using a Hall probe array. No clear evidence for the spontaneous magnetic field, accompanying the time-reversal symmetry breaking states, has been obtained. Magnetization with H_a∥_c shows an anomaly close to H_c2 and a peak near H_a = 0. We interpret the former to be due to the synchronization peak effect. H_c1 or change in the vortex lattice structure could be relevant to the latter.
