Peculiar features of electron spin resonance spectra in (Ca,Na)-doped lanthanum manganites

Peculiar features of electron spin resonance spectra in (Ca,Na)-doped lanthanum manganites

The analysis of the ESR spectra for the powdered samples of (Ca,Na)-doped manganites have been performed in the temperature range 220–320 K. It is shown that the samples under investigation are characterized by a broadened para- to ferromagnetic transition and complicated spectra within the transiti...
