The transition from dynamics to statics in the electron-spin-resonance spectra of impurity Mn2+ ions in strontium titanate
Original language description
The electron- spin -resonance (ESR)spectra of SrTiO3:Mn single crystals have been investigated.Results unambiguously indicate that the impurity center formed by an Mn2+ ion has a dynamic nature. In the high temperature range (T > 100 K), ESR spectra of Mn2+ ions reveal cubic symmetry; the spectrum is found to broaden significantly with a decrease in temperature. Upon cooling to T < 10 K, low symmetry centers of Mn2+ ions with a strong orientational dependence emerge in the spectra. Temperature evolutionof the ESR spectrum can be described within the model of a dynamic off- center Mn2+ ion substituting for the Sr2+ ion, with a transition to the static regime at low temperatures with an average localization energy of 2.4 0.4 meV for Mn2+ centers due torandom deformations.
