Abstract	:	Using a two-coil mutual inductance method, we have measured the inductance ofpinned vortices in YBazCu307-6 and Lal.&r~.lsCuO~ thin films. We present data ontwelve films grown using three different techniques: coevaporation with post annealing,pulsed laser deposition, and RF sputtering. We present a detailed analysis of the datausing 3 model based on a low density of planar defects and a high density of extendeddefects. From our analysis. we conclude that pulsed laser deposition produces the highestdensity of pinning defects while coevaporation produces the lowest density. The filmsstudied have sufficient planar defects to accommodate roughly 500 Gauss of vortices.The linear extended defects extinguish superconductivity within a radius of 4 A to 8 A.The density of extended defects is roughly 7x 10'' pm-'.
