Flux pinning in PrFeAsO0.9 and NdFeAsO0.9F0.1 superconducting crystals

Owing to both the extreme thermodynamic characteristics in which their growth takes place and a complex crystallographic polymorphism upon cooling, cubic rare-earth

Abstract.- Pinning in a type II superconductor with periodically distributed inhomogeneities is "lo- cal" only below the "inversion temperature" T. For T>T , due

Abstract.- Resistivity measurements in CeB6 show-a pronounced anomaly of the Fisher-Langer type at 2.5 K Magnetic susceptibility and magnetization reveal a strong magnetic

These results suggest that the structural transformation begins at a pretty higher temperature, accompanies enhanced thermal expansion and attains to T with the largest a.. It
