We present zero-field Mn-55 NMR spectra from two single crystals of La1-xSr1+xMnO4 (x = 0 and 0.5). Both samples exhibit resonance peaks at much lower frequencies than in the pseudocubic manganites. The dependence of the peak positions on doping cannot be simply accounted for by charge transfer from Mn3+ ions.

Abstract
We present zero-field Mn-55 NMR spectra from two single crystals of La1-xSr1+xMnO4 (x = 0 and 0.5). Both samples exhibit resonance peaks at much lower frequencies than in the pseudocubic manganites. The dependence of the peak positions on doping cannot be simply accounted for by charge transfer from Mn3+ ions.File in questo prodotto:
