The results of the resistive measurements on the LuNi$_{2}$B$_{2}$C layer deposited under opti- mized conditions ( T = 830 ℃ , f = 5 Hz) are shown in Fig. 5 (a) and (b). The external magnetic field H was aligned parallel to the c–axis of the borocarbide which here is parallel to the normal axis of the films. The transition curves are quite steep as seen in Fig. 5(b) and the slight broadening for higher magnetic fields, caused by fluctuations in the film, is known from crystalline samples as well [29]. The residual resistivity ratio (RRR) of the film was
