Sign reversal of the Hall resistance in the mixed-state of La1.89Ce0.11CuO4 and La1.89Ce0.11(Cu0.99Co0.01)O4 thin films

► We change the pinning environment in superconductors to achieve different Hall resistance sign reversals. ► Double sign reversal in the Hall resistivity has been revealed in the electron-doped LCCO thin films. ► Co doped LCCO thin films provide weak pinning strength for the double sign reversal of the Hall resistivity. ► Double sign reversal of Hall resistance can be achieved by tilting the magnetic field in the LCCO thin films.
