Abstract: | We measured the in-plane magnetoresistance of Pr0.9LaCe0.1CuO4 (PLCCO) epitaxial thin films under various magnetic fields H applied parallel to the tetragonal c-axis. The measurements were performed at the superconducting state as well as the normal state. As the magnetic field is between the low critical field Hc1 and upper critical field Hc2, a critical scaling behavior of electrical resistivity is found. We analyze the electrical transport properties and show the magnetic field H dependence of glass transition temperature Tg and the characteristic temperature T* for the PLCCO film, which may shed some light on vortex behavior in electron-doped superconductors. |
