Abstract Electron paramagnetic resonance (EPR) spectra of manganese-doped strontium titanate were investigated for several Mn concentrations. The spectra of Mn2+ and Mn4+ ions were observed and attributed, respectively, to Mn ions occupying Sr2+ and Ti4+ sites. The relative intensity of the spectra suggested that the manganese ions occupy preferentially Ti4+ sites. The results showed that the EPR peak-to-peak linewidth of the Mn4+ spectrum increases with manganese concentration according to the theoretical equation DHpp=0.45+210.f.(1-f)80 (mT). This suggested that the exchange interaction between tetravalent manganese ions in strontium titanate has an approximate range of 0.96 nm, comparable to that of Gd3+ in the same compound.
