Abstract

The longitudinal (ρ_xx) and transverse resistivities (ρ_xy) were examined in order to study the effect of flux pinning in the YBa₂Cu₃O_y/PrBa₂Cu₃O_y (YBCO/PBCO) superlattices. It was observed that the sign reversal of Hall coefficient R_H diminished with a decreasing thickness of the individual YBCO layer or with increasing thickness of the individual PBCO layer. The exponent β in scaling behavior ρ_xy∼ρ^β_xx is magnetic field dependent and the dependence is stronger for a YBCO/PBCO superlattice with a thinner YBCO layer.
