Image of FIG. 1.
FIG. 1.

(a) Resistivity-temperature and (b) normalized magnetization-temperature graphs of potassium-doped thin films. The normalized magnetization is measured at . The inset of figure (a) is a magnified view near the superconducting transition temperature. The film grown on (0001) shows a higher than the film deposited on (001). The clear diamagnetic signals in (b) indicate the good bulk superconductivity of our samples. The inset of (b) shows the surface morphology of a film grown on a substrate.

Image of FIG. 2.
FIG. 2.

X-ray diffraction spectra ( scans) of potassium-doped thin films grown on (0001) and (001) substrates. These curves indicate that the films are preferentially oriented along the -axis, regardless of the substrate.

Image of FIG. 3.
FIG. 3.

The temperature dependences of the resistivity of a potassium-doped thin film fabricated on an substrate, measured in fields up to 7 T. The inset show the temperature dependence of the upper critical magnetic field, where the upper critical magnetic field was determined as the field at where the resistivity dropped 90%, 50%, or 10% from its normal-state values at 41 K.
