摘要：
The electron spin resonance (ESR) spectra of electron-doped La0.9Sb0.1MnO3 with colossal magnetoresistance effect have been studied in this paper. The ESR results demonstrate that there is magnetic phase separation and complex magnetic structure. The compound changes from ferromagnetic to paramagnetic state gradually with increasing temperature. Ferromagnetic and paramagnetic phases coexist in the wide transitional temperature range. The ESR absorption spectra have been fitted by Lorentzian curves and the magnetic phase evolvement with temperature has been analyzed.
