摘要

We have attempted to measure the second har- monic generation (SHG) of YBa2Cu3O7- δ(YBCO) epitaxial films grown on (001) MgO substrates by laser ablation. Since the structure of the film has inversion symmetry, the possibly SHG susceptibility can only be attributed to the antifer-romagnetic dipoles and electric quadrupoles. The delicate and meticulous experiment shows that the angular dependence of the second harmonic susceptibility of the superconducting films can be fitted successfully by the time-dependent density functional approach.
