We measured the angular dependence of critical currents on YBa2Cua0r_y/
Pr,Y1_,BazCus07_y superlattices at various applied magnetic fields and temperatures
to investigate the effect of layer coupling on the dimensionality of the superlattices. The
applied magnetic field was up to 6 Tesla and the temperatures varied from T, to about
50 K. The angie between ‚he applied magnetic field and the c-axis of superlattices
were from 0” to 180lc. The current was always perpendicular to the applied magnetic
field. The Kes model was introduced to fit our data to study the dimensionality of the
superlattices. For sample where the coupling is weak, the 2D Kes model has better
fitting. These results will be discussed.
