    The temperature dependence of Mn2+ and Mn4+ EPR spectra strongly indicates the formation of MnO2 or MnO small particles to be the favored configuration for the Mn insertion in SrTiO3. Only a part of manganese ions incorporates into the crystal lattice in B position as Mn4+ ions.

    Teplotní závislost EPR spekter Mn2+ a Mn4+ v SrTiO3 ukazuje na formování MnO2 a MnO malých částic v souladu s příznivou konfigurací pro inkorporaci Mn do mřížky SrTiO3.Pouze část příměsí Mn ve formě Mn4+ iontů obsazuje v krystalové mřížce tzv. pozici "B".
