Résumé

The influence of the magnetic history on the structure of the vortex solid has been investigated by small angle neutron scattering in the cubic (K,Ba)BiO₃ superconductor. The diffracted intensity strongly depends on the cooling procedure for 0.3<μ₀H<0.7T (at 2.5 K) showing that defects can be quenched into the vortex solid in this field range. For all cooling procedures, the diffracted intensity tends towards zero for μ₀H=B_NLt;B_c2 (B_N~1.5T at 2.5 K) for all cooling procedures. The corresponding B_N(T) line is discussed in comparison with the field induced order-disorder transition theory.
