- Abstract
The temperature behavior of the [SUP139]La and [SUP19]F NMR spectra was studied for polycrystalline LaMn(O[SUB1 - x]F[SUBx])[SUB3] with a partial substitution of fluorine for oxygen. The temperature dependences of the [SUP139]La and [SUP19]F NMR line shapes were found to be substantially different. An appreciable broadening of the [SUP19]F NMR spectrum and a fixed position of line maximum with lowering temperature is indicative of the presence of a short-range magnetic order in the paramagnetic temperature region (T > T[SUBN]).
