Papavassiliou et al. /Phys.Rev.B 58, 12237, 1998/ observed "apparently strange"Mn NMR line shape and T₂ versus frequency dependence in La_0.67Ca_0.33MnO₃. The authors believe that the NMR signal originates in the domain walls and that the electron hole density varies across the domain wall for T<80 K.
