    • Effects of Mn doping on dielectric properties of ferroelectric relaxor PLZT ceramics 

      Dimza, Vilnis; Popov, Anatoli I.; Lāce, Lelde; Kundzinš, Māris A.; Kundziņš, Kārlis; Antonova, Maija K.; Livinš, Maris G. (Elsevier B.V., 2017)
      A series of PLZT (8/65/35) ceramics with different Mn2O3 concentration (0.01, 0.1, 0.3, 1.0, and 3.0% by weight) have been synthesized to figure out its influence on their dielectric properties. The complex dielectric ...

    • Local structural investigation of hafnia-zirconia polymorphs in powders and thin films by X-ray absorption spectroscopy 

      Schenk, Tony; Anspoks, Andris; Jonane, Inga; Ignatans, Reinis; Johnson, Brienne S.; Jones, Jacob L.; Tallarida, Massimo; Marini, Carlo; Simonelli, Laura; Hönicke, Philipp; Richter, Claudia; Mikolajic, Thomas; Schroeder, Uwe (Elsevier Ltd., 2019)
      Despite increasing attention for the recently found ferro- and antiferroelectric properties, the polymorphism in hafnia- and zirconia-based thin films is still not sufficiently understood. In the present work, we show that ...

    • Polarization and acoustic properties of barium-modified lead-free potassium–sodium niobate ceramics 

      Bormanis, Karlis; Burkhanov, Anver I.; Sternberg, Andris; Zhirkov, Aleksandr V.; Antonova, Maija; Kalvane, Anna; Ignatans, Reinis (Estonian Academy Publishers, 2017)
      Results of polarization and polarization switching in samples prepared by solid phase synthesis of the (1-х)(K0.5Na0.5)(Nb0.93Sb0.07)O3–xBaTiO3 + 0.5mol%MnO2 system at x = 0.01, 0.02, and 0.04 (KNNS7–xBT) studied over a ...
