Abstract The mixed state of the YBaCu2O6.9 superconducting ceramics is investigated by neutron depolarization (ND). The magnetic flux penetration into superconductor's granules can be described in terms of Bean's critical state model. The field and temperature dependence of the average angle of the vortex line deflection from the direction of the applied magnetic field are determined. In particular, this angle is zero atT/T c ∼0.5 andH/H c2∼0.015, which is at the sameT/T c nearH/H c2∼0.017 for the metalloceramic SnMo6S8 superconductor. The latter is also studied in the present work for comparison with the YBa2Cu3O6.9 sample. TheseH/H c2 are far below the corresponding values ofH/H c2 for Nb, Nb−Ta. The creep of the flux line misalignments from the applied field direction is examined.
