Electrical Studies of Barkhausen Switching Noise in Ferroelectric lead zirconate titanate (PZT) and BaTiO3: Critical Exponents and Temperature-dependence
C. Flannigan, C. D. Tan, J. F. Scott
Previous studies of Barkhausen noise in PZT have been limited to the energy spectrum (slew rate response voltages versus time), showing agreement with avalanche models; in barium t…

Plasmon Soft Mode in an Organic-Inorganic Hybrid Perovskite
Jiyu Tian, Karuna Kara Mishra, Eli Zysman-Colman +3
We report inelastic light scattering from underdamped plasmons in azetidinium lead bromide (AzPbBr3). The plasmons are very strongly temperature dependent and serve as a soft mode…
