中文摘要	Magnetization measurements have been performed on C-axis oriented superlattice films of YBaCuO/PrBaCuO in wide ranges of temperature T (4.2-70 K) and magnetic field H (0-8 T) with H(parallel-to) C-axis. Pinning-force scaling has been found with the form f(p)=A(1-t)2.7 h(m)(1-h)n, m=0.9, n=1.8 for sample 28# (48 angstrom/100 angstrom), and m=0.7, n=3 for sample 29# (48 angstrom/24 angstrom). This result indicates that flux pinning centers in YBaCuO/PrBaCuO films are strong in a wide range of the field h so that F(p) has a domelike dependence on magnetic field. The dependence of m and n on the samples with different thickness of the PrBaCuO layer manifests that the dynamic property (C44 and C66) of the flux-line lattice plays an important role in the volume pinning-force density F(p)(T, H). The deviation of F(p) from the scaling law in high reduced field h may be explained by giant flux creep or collective pinning.
