dc.descriptionWe present and analyze field cooled magnetization data, revealing for 0<H<5 T remarkable consistency with a magnetic field induced finite size effect. It is traced back to the fact that the correlation length gsi cannot grow beyond the limiting length scale LH set by the magnetic field, where at temperature Tp(H), gsi(T) = LH. Thus, in sufficiently homogeneous samples and nonzero H the transition from the superconducting to the normal state turns out to be smooth and the appropriately scaled magnetization data fall near Tp(H) on a universal curve. Consistent with the generic behavior of optimally doped cuprates we also show that the pressure effect on Tc is negligibly small, while the negative value of the relative volume change mirrors that of the ansisotropy.
