摘要：

The motion of the flux lines (FL) in high temperature superconductors and their relationship with the NMR quantities are reviewed and discussed in the light of recent Y-89 NMR experiments in YBCO-type compounds. Tn particular measurements involving the Y-89 Spin echo attenuation induced both by the thermal excitation of the FL's and by motions driven by DC current and pulsed magnetic fields are presented, with preliminary results and lines of interpretation. Flux line motion as observed with Hg-199 NMR in HgBa2CuO4+delta high temperature superconductor is discussed.
