NMR study of LaMn1-xCoxO3 perovskites
Abstract
The perovskite compounds of LaMn1-xCoxO3 (0.2⩽x⩽0.5) have been studied by means of NMR spectroscopy in powder samples prepared by the solid state reaction and sol-gel methods. The NMR signals were observed in the frequency range 250-650 MHz at 4.2 K in zero external magnetic field. A relatively narrow spectral line assigned to 55Mn in Mn is situated around 270-320 MHz in all spectra. Additional spectral lines are observed at higher frequencies. Line intensities and forms are dependent on the cobalt concentration and preparation techniques.
