N2 - The magnetic vortex phase diagram of (Formula presented) was measured using a Hall sensor array. Pb doping was shown to drastically change the magnetic phase diagram including a significant increase in the irreversibility field and a temperature dependence of the onset field of the second magnetization peak. Anisotropy was determined using a recently proposed scaling expression, which relates the anisotropy to the irreversibility line. Based on the obtained anisotropy an excellent fit of the experimental (Formula presented) data to the model of disorder-induced transition was found for three basic regimes: (Formula presented) for (Formula presented) K, (Formula presented) for (Formula presented) K, and (Formula presented) for (Formula presented) K, where s, (Formula presented) and (Formula presented) are, respectively, the interlayer spacing, the characteristic size of the longitudinal fluctuations in a cage, and the size of a coherently pinned vortex segment.
