Abstract

In Pr0.7Ca0.15Ba0.15MnO3 manganite, the spin dynamics is studied by the method of electron paramagnetic resonance (EPR). The analysis showed that at the temperature ТLTmin, which corresponds to the minimal width of the EPR line, the shape of lines of absorption spectra is perfectly described by a single Lorentzian. At other temperatures (not ТL), the absorption lines of the EPR spectra are asymmetric, which is caused by their exchange broadening at Т < ТL or hopping conductivity at T > ТL.
