Abstract
The zero-field electrical transport properties of 24 degrees [001] til t bicrystal grain boundaries in YBa2CU3O7 were found to be in excellen t agreement with the Ambegaokar-Halperin model over an extended range of currents and voltages. This model gives a firm basis for characteri zing and comparing boundaries, and provides two independent measures o f the critical current, which were proportional to (1 - T/T-c)(2) clos e to the transition temperature T-c.
