EPR study of the Mn-doped magnesium titanate ceramics
Original language description
Manganese-doped magnesium titanate ceramic samples obtained by a solid-state reaction via sintering in the air from a mixture of MgO and TiO2 powders of different molar ratios were analyzed by electron paramagnetic resonance (EPR) technique. The EPR signals of Mn2+ ions (S = 5/2, CYRILLIC CAPITAL LETTER BYELORUSSIAN-UKRAINIAN I = 5/2) in crystal phases of MgO, Mg2TiO4, and MgTiO3 were detected. We have obtained the following spin Hamiltonian parameters for Mn2+ ions: g = 2.0015, A similar to 81.0 x 10(-4) cm(-1) (in MgO phase),g = 2.0029, A similar to 73.8 x 10(-4) cm(-1) , b (2) (0) = 35 x 10(-4) cm(-1) (in Mg2TiO4 phase), g = 2.0040, A similar to 79.0 x 10(-4) cm(-1) , b (2) (0) = 165 x 10(-4) cm(-1) (in MgTiO3 phase). Despite the presence of Mn4+ centers in both Mg2TiO4:Mn and MgTiO3:Mn ceramics confirmed by previous optical studies, no EPR signals related to Mn4+ ions (S = 3/2, CYRILLIC CAPITAL LETTER BYELORUSSIAN-UKRAINIAN I = 5/2) were found. The Mn2+ EPR signals are proposed as structural probes in manganese-doped magnesium titanate ceramics.
