FIG. 4: (color online). X–ray phi scan of a LuNi$_{2}$B$_{2}$C film on MgO(110) deposited at 5 Hz at 830 ℃ . The (112) reciprocal lattice plane at ψ = 65 ° was used for the measurement. The in–plane full width at half maximum (FWHM) is about 1 ° (Gaussian fit in the inset). studies on borocarbide thin films. The superconductive properties of the prepared LuNi$_{2}$B$_{2}$C films were studied with resis- tive measurements in a Quantum Design PPMS . The films were resistively characterized in the as–prepared state using a four-point resistivity measurement, where the four contacts were linearly aligned in a row and placed about 2 mm from the sample edge. The results of the temperature series prepared with a laser repetition rate of 20 Hz are summarized in table 1. It is apparent that the critical temperatures of these films with a value of 14 to 15.1 K are considerably below the bulk value of up to 16.5K. However, the increasing critical tem- peratures with increasing deposition temperature up to 840 ℃ clearly point out that with improved phase formation and in–plane texture intensity, better superconducting properties are achieved. For a deposition temperature of 880 ° however, the superconducting transition is dramatically broadened and the sample eventually becomes completely superconducting at a very low temperature of about 4 K only. We conclude that the superconducting phase is affected by increased interdiffusion of impurity phases from the interface into the film at 8 IV. SUPERCONDUCTIVE PROPERTIES
