Abstract

We demonstrate the magnetic-field distribution of the pure vortex state in lightly doped (formula presented) powder samples, by using (formula presented) nuclear magnetic resonance in magnetic fields of 23.5 and 47 kOe. The magnetic-field distribution at (formula presented) is Al-doping dependent, revealing a considerable decrease of anisotropy in respect to pure (formula presented) This result correlates nicely with magnetization measurements and is consistent with (formula presented)-band hole driven superconductivity for (formula presented).
