Imaging ferroelectric hysteresis and domain wall pinning
S. Bhattacharya, M. J. Higgins
Simultaneous imaging of the piezoresponse phase, amplitude and bare surface topography of displacive ferroelectric thin films by scanning probe microscopy directly shows the nature…
AC Dynamics and Metastability of a Flux-Line Lattice
W. Henderson, E. Y. Andrei, M. J. Higgins +1
We have measured the complex surface impedance of 2H-NbSe_2 in the mixed state over a wide range of magnetic field(0-2T) and frequency(10-3000MHz). A crossover between pinned and v…
Nature of Phase Transitions of Superconducting Wire Networks in a Magnetic Field
X. S. Ling, M. J. Higgins, Chao Tang +8
We study - characteristics of periodic square Nb wire networks as a function of temperature in a transverse magnetic field, with a focus on three fillings 2/5, 1/2, and 0.618…
Peak Effect in Superconductors: Melting of Larkin Domains
Xinsheng Ling, Chao Tang, S. Bhattacharya +1
Motivated by the recent observations of the peak effect in high- YBCO superconductors, we reexamine the origin of this unusual phenomenon. We show that the mechanism based on…
