Figure 3
Magnetic-Temperature phase diagram for H||ab. The closed symbols (experimental results) and solid lines (guides to the eye) represent the lower crossover line μ0Hcr1(T) for (a) pristine and (b) nanocomposite films. The open symbols (experimental results) and dashed line (guide to the eye) represent the upper crossover line μ0Hcr2(T). The dotted line with open circles refers to the experimental irreversibility line. Crossover points are plotted for a large variety of samples, identifying three typologies of nanocomposites (in three different colors) regarding the region of μ0Hcr1(T). The insets show the S(θ) dependence for a pristine sample in the regions of the diagram separated by the crossover lines in figure (a).
