Studies by neutron diffraction and {mu}SR of flux lattice orientation, pinning, melting and decomposition in high-T{sub c} superconductors

Description: We review the results of recent microscopic measurements of flux line structures and their breakdown in the high-Tc superconductors BSCCO and YBCO. These results show clear effects of flux of lattice melting, dimensional crossover and pinning. The huge differences in behaviour of the flux lattice in these two materials can be understood theoretically.

Vortex lattice structures in YNi{sub 2}B{sub 2}C

Description: The authors observe a flux lattice with square symmetry in the superconductor YNi{sub 2}B{sub 2}C when the applied field is parallel to the c-axis of the crystal. A square lattice observed previously in the isostructural magnetic analog ErNi{sub 2}B{sub 2}C was attributed to the interaction between magnetic order in that system and the flux lattice. Since the Y-based compound does not order magnetically, it is clear that the structure of the flux lattice is unrelated to magnetic order. In fact,… more

Neutron scattering from the flux lattice in high temperature superconductors

Description: Neutron scattering has been used to observe diffraction from the flux-line lattice in high temperature superconductors. This technique is particularly useful in such systems as it allows observations to be made over a wide range of temperature and magnetic field. Experiments on the systems K{sub 0.4}Ba{sub 0.6}BiO{sub 3} and YBa{sub 2}Cu{sub 3}O{sub 7--8} will be described with applied magnetic fields of up to 4 Tesla and for temperatures from 2K to {Tc}.
