| Abstract(in English) | We have fabricated c-axis oriented YBaCuO / PrBaCuO / YBaCuO trilayer junctions on an LAST single crystal as a new substrate. The junctions showed RSJ-like current-voltage characteristics with hysteresis, and modulation of critical current by the external magnetic field. The typical junction with a dimension of 4×4μm^2 and a PrBaCuO barrier thickness of 20nm had a critical current I_c of 14μA, a junction resistance R_n of 118Ω, and an I_cR_n product of 1.4mV. By changing the thickness of PrBaCuO barrier ranging from 20nm to 35nm, it is found that J_c is exponentially decreased and R_nA is exponentially increased as the barrier thickness is increased. The decay length values of J_c and R_nA are estimated to be 5.3nm and 1.3nm, respectively. These values are less than those of(103)oriented YBaCuO trilayer junctions, which may be due to the shorter coherence length of c-axis oriented junctions compared to(103)oriented junctions |
