Suppression of the Melting Line in a Weakly Disordered Flux-line System
Gautam I. Menon, G. Ravikumar, M. J. Higgins +1
An analytic formula describing the suppression of the equilibrium melting line by quenched point pinning disorder is compared to data from ac susceptibility and magnetization measu…
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…
Structure of the flux lines lattice in NbSe2: Equilibrium state and influence of the magnetic history
A. Pautrat, M. Aburas, Ch. Simon +5
We have performed small-angle neutron scattering (SANS) of the flux line lattice (FLL) in a Fe doped NbSe_2 sample which presents a large peak effect in the critical current. The s…
Manifestation of modulation in spatial order of flux line lattice in weakly pinned superconductors : a vibrating sample magnetometer study
A. D. Thakur, D. Pal, M. J. Higgins +2
We have investigated the healing of transient disordered vortex states injected into a superconducting sample during the field ramping process in isothermal M-H measurements as a p…
Why pinning by surface irregularities can explain the peak effect in transport properties and neutron diffraction results in NbSe2 and Bi-2212 crystals?
Charles Simon, Alain Pautrat, Christophe Goupil +6
The existence of a peak effect in transport properties (a maximum of the critical current as function of magnetic field) is a well-known but still intriguing feature of type II sup…
Evolution in the split-peak structure across the Peak Effect region in single crystals of -NbSe
A. D. Thakur, T. V. Chandrasekhar Rao, S. Uji +4
We have explored the presence of a two-peak feature spanning the peak effect (PE) region in the ac susceptibility data and the magnetization hysteresis measurements over a wide fie…
