    • Control of ferroelectrcity in ATiO₃ (A= Ba₁ and Sr) by isoelectronic Ti-site substitutions 

      Alfurhud, Saber (Northern Illinois University, 2018)
      This thesis presents the results of investigation of structural and ferroelectric changes when the (Ba₁Sr)TiO₃ systems are substituted by the smaller size elements into the Ti-site, while controlling the tolerance factor ...
    • Discovery and study of single-phase and single-ion manganese perovskite multiferroics 

      Chapagain, Kamal (Northern Illinois University, 2019)
      Multiferroic materials having unusual properties of simultaneous presence of ferroelectricity (FE) and magnetism, such that FE can be controlled by magnetic field and magnetization by electric field have attracted interest ...
    • Hexagonal manganites for gas separation 

      Alanizy, Maleeha (Northern Illinois University, 2017)
      This thesis discusses results of study of hexagonal manganites of RMnO[sub 3+[delta]] (R= Ho, Y) and Y[sub 1-x]R[sub x]MnO[sub 3+[delta]] (R = Gd and Tb) for potential air-separation applications. Structural and oxygen ...
    • Oxygen storage and electrolyte materials of RMnO₃ 

      Allahyani, Wadiah (Northern Illinois University, 2017)
      This thesis presents the results of investigation of the (Y,Ce)MnO₃ system and the phase diagram of the (R[sub 1-x]R[sub x])-(In[sub 1-y]Mn[sub y])O₃ system for the stability of the hexagonal structure and the presence of ...
