Comment on ''NMR in manganese perovskites: Detection of spatially varying electron states in domain walls''

Papavassiliou [Phys. Rev. B >58, 12237 (1998)] observed {open_quotes}apparently strange{close_quotes} {sup 55}Mn NMR line shape and T{sub 2} versus frequency dependence in La{sub 0.67}Ca{sub 0.33}MnO{sub 3}. 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{lt}80K. Their conclusion is that the charge variation in the domain walls is responsible for the observed strong magnetoresistivity at low temperatures. We suggest that the {open_quotes}strange{close_quotes} line shape is likely to result from the experimental conditions and not from the spatial variation of the charge density.
