Abstract

The tunneling spectrum of the superconducting 3-K phase of Sr₂RuO₄ with cleaved junctions was measured. Andreev surface bound states were observed in the region below 3K which gave rise to a sharp zero-bias conductance peak (ZBCP). The Andreev reflection indicated that the phase of the pairing amplitude depended on the direction. A crossover from sharp to bell-shaped ZBCP was observed below the bulk T_c which supported a phase transition in the 3K-phase region near the bulk T_c.
