The electrical resistivities of thin films of Yl\_xPrxBazCu307 a and Nd~ xCexBazCu307 a have been measured as a function of temperature, magnetic field and concentration x. The p(T, x) behavior of the metastable Ce-doped samples closely follows that of the Pr-doped compounds, suggesting that the dep
