Abstract

Small Angle Neutron Scattering has been used to investigate the structure of the flux line lattice in the isotropic (K, Ba)BiO₃ high T_c compound. The flux lines are well ordered into a hexagonal lattice at low field (H < H_e approx. 0.6T ≪ H_g(0) where H_g is the second order vortex glass transition field) but dislocations become energetically favorable above H_e leading to a glassy structure. Moreover, the orientationnal order is partially lost in the vicinity of the entanglement transition but can be recovered by slightly oscillating the field during the cooling process.
