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 Hac shows an anomaly close to Hc2 and a peak near Ha = 0. We interpret the former to be due to the synchronization peak effect. Hc1 or change in the vortex lattice structure could be relevant to the latter.
