Quantum Critical Point study in Multiferroic Hexaferrites: BaFe12O19, SrFe12O19, and PbFe3Ga9O19 -- Verification of the Khmelnitskii Theory
S. E. Rowley, Yi-sheng Chai, Shi-peng Shen +4
BaFe12O19 is a popular M-type hexaferrite with T(Neel) = 720 K of enormous commercial value (3 billion dollars/year). It exhibits an incipient ferroelectric phase transition (in vi…

Faceting Oscillations in Nano-Ferroelectrics
J. F. Scott, Ashok Kumar
We observe periodic faceting of 8-nm diameter ferroelectric disks on a 10 s time-scale when thin Pb(Zr0.52Ti0.48)O3 (PZT) film is exposed to constant high-resolution transmission e…

Ferroelectric and Photovoltaic Properties of Transition Metal doped Pb(Zr0.14Ti0.56Ni0.30)O3-delta Thin Films
Shalini Kumari, Nora Ortega, Ashok Kumar +2
We report nearly single phase Pb(Zr0.14Ti0.56Ni0.30)O3-delta(PZTNi30) ferroelectric having large remanent polarization (15-30 μC/cm2), 0.3-0.4 V open circuit voltage (VOC), reduced…
