Sr- and Ti-site substitution, lattice dynamics, and octahedral tilt transition relationship in SrTiO3:Mn ceramics
Original language description
SrTiO3:Mn ceramics, prepared according to the chemical formulae Sr1-xMnxTiO3 and SrTi1-yMnyO3, are studied by Fourier transform infrared and time-domain terahertz spectroscopy . Polar soft mode hardens in the whole temperature range by the substitution of Mn ions on Ti sites, but only in the low-temperature range by the Sr site substitution. Activation of the mode, associated with the R point condensation of the Brillouin zone below the structural transition temperature Ta shows that the substitution onthe Sr sites increases Ta whereas the Ti-site substitution suppresses Ta.
