Description

We have investigated YBCO grain boundary junctions formed on YSZ bicrystal (0-32 ) substrates. We observed strong magnetic field dependent peaks in the Josephson current for certain voltage biases. We relate the structures to self-induced Fiske steps, where the junction electrodes along the grain boundary form a resonator of length L, and the ac Josephson current sets up a standing wave for frequencies fn = n. c/2L. For L = 20 μm, resonances occurred at f1 = 280 GHz, f2 = 490 GHz, f3 = 640 GHz. A good agreement between the calculated Fiske-modes and the experimental dependence was obtained. (orig.)
