Current densities (Formula presented) and volume pinning forces (Formula presented) are obtained in a wide temperature (Formula presented) and field range (Formula presented) on different (Formula presented) samples. Above 60 K a good scaling of the volume pinning force (Formula presented) versus the reduced field (Formula presented) can be established. The scaled pinning curves are compared to several theoretical predictions. Experimental evidence for strong pinning at extended superconducting defects (interaction volume (Formula presented)) is given. These defects are ascribed to spatial composition fluctuations found in light rare-earth superconductors, providing a scatter of the transition temperature (Formula presented) Such a pinning mechanism is especially important for applications of high-(Formula presented) superconductors operating at (Formula presented).
