Characterizing oxygen atoms in perovskite and pyrochlore oxides using ADF-STEM at a resolution of a few tens of picometers
Ali Mostaed, Brant Walkley, Monica Ciomaga Hatnean +5
We present an aberration corrected scanning transmission electron microscopy (ac-STEM) analysis of the perovskite (LaFeO3) and pyrochlore (Yb2Ti2O7 and Pr2Zr2O7) oxides and demonst…

Dielectric spectra of a new relaxor ferroelectric system Ba2LnTi2Nb3O15 (Ln=La, Nd)
S. Kamba, S. Veljko, M. Kempa +7
New relaxor ferroelectric system has been synthesized. BLTN exhibits a smeared maximum of permittivity, characteristic of classic relaxor behaviour, with a peak shift from 185 K at…

Temperature dependence of microwave and THz dielectric response in Srn+1TinO3n+1 (n=1-4)
D. Noujni, S. Kamba, A. Pashkin +6
The microwave, near-millimetre and infrared (IR) dielectric response of Srn+1TinO3n+1 (n=1-4) Ruddlesden-Popper homologous series was studied in the temperature range 10 to 300 K.…
