Abstract

We review the detection of flux lattice structure by neutron diffraction and describe recent results of this technique in YBa₂Cu₃O_7-δ. We have observed flux lattice structures in fields up to 4T, which is the highest field at which the mixed state has been imaged in any superconductor. There is strong pinning of flux lattice planes to twin planes and no clear signs of melting of the flux lattice in this material. The distortion of the flux lattice structure by the crystal anisotropy has also been observed.
