BSCCO superconductors processed by the glass-ceramic route
Glassy Bi-Sr-Ca-Cu-O (BSCCO) precursors were prepared by different melt-quenching methods to investigate the melt properties of the BSCCO system before the crystallization investigations were started. In order to fabricate superconductors having high critical temperature and current density using …

Inelastic X-ray scattering studies of broken symmetry in BSCCO
… of acoustic phonons in single and double layer BSCCO which show several effects: broadening of the longitudinal acoustic in correspondence to approximately period-four ordering tendencies and signatures of time-reversal and inversion symmetry breaking. Measurement of these anomalous properties …

Interaction between vortices and impurities in a d-wave superconductor /
… the scanning tunneling microscopy (STM) data in BSCCO. We introduce the Bogoliubov-De Gennes Hamiltonian and solve it numerically on a two-dimensional 20 x 20 lattice under a magnetic field perpendicular to the surface. We consider a vortex at the center of our model. We introduce a Zn impurity …

X-Ray scattering investigations of subtle ordering in correlated materials
… dichroism at the copper K-edge in double-layer BSCCO suggest breaking of inversion symmetry in the pseudogap. We perform copper K-edge dichroism measurements on carefully aligned BSCCO. Azimuthal rotations reveal the circular dichroic signal the result of linear bleed through. Polar rotations …

Electrical characterization of high temperature superconductors as a function of temperature
… sheathed multifilamentary Bi 2Sr 2Ca2 Cu3010 (BSCCO- 2223/Ag) tapes at temperatures ranging from 77 K to 110 K were measured using a typical four-terminal technique for two different BSCCO-2223/Ag tapes manufactured by Vacuumschmelze (VAC). The critical currents for the two VAC samples were …

Design and optimisation of a coreless superconducting synchronous generator
… undertaken for a demonstrator size machine with BSCCO windings. But to achieve real benefits it is important to build a machine that more closely represents real machines. Hence an optimisation method is used to investigate the possibility of increasing the size of the machine.

Investigation of renormalization effects in high temperature cuprate superconductors
While in conventional superconductors coupling between electrons and phonons is known to be responsible for the electron pairing, for the high temperature superconductors the pairing media remains under debates. Since the interactions of electrons with other degrees of freedom (phonons, magnetic …

Variable Temperature Scanning Tunneling Microscopy Study of a High Temperature Superconductor Bi2Sr2CaCu2O8+d
We have used a custom-built scanning tunneling microscope (STM) to investigate the electronic states of a slightly underdoped high-TC superconductor Bi2Sr2CaCu2O8+d as a function of temperature. We have demonstrated for the first time that atomicallyresolved spectroscopic studies at elevated …
