Abstract

The magnetoresistance (MR), which depicts the nature of dissipation in Bi₂Sr₂Ca_1−xY_xCu₂O_8+δ thin film, was investigated at different temperatures and applied fields. A MR peak (MR_max) occurs at the same temperature for different magnetic fields for the same Y concentration. MR_max varies linearly with the applied magnetic field due to the increase in the number of vortices contributing to the dissipation as the magnetic field is raised. However, Y-doping decreases MR_max with increasing magnetic field application. This observation suggests that increasing the Y content improves the coupling strength between the CuO planes, which limits the motion of the pancake vortices, and thus reducing the dissipation.
