Growth-induced linear defects are shown to strongly affect the microwave surface resistance, Rs, of highly biaxially oriented high temperature superconductor (HTS) YBa2Cu3O7-δ (YBCO) films. Measured R,(77 K) turned out to be 4-5 times higher than in single crystals. The films were deposited by modified pulse-laser technique, Ic(77 K) = (3 - 6) x 106 A/cm2, onto LaAlO3substrates, Rs(T) was measured at 134 GHz and 20-100 K. TEM/HREM study of YBCO films deposited at Ts = 750°C-780°C revealed a reduction of edge dislocation density with Ts increase (from 2.1011 to 1010 lines/cm2). YBCO films deposited at Ts = 780°C exhibited the smallest Rs(77 K, 134 GHz) < 120 mΩ and the lowest density of dislocations detected by HREM and X-ray analysis. A nature of the dislocation effect is discussed within a model of local anisotropic elastic deformation in a vicinity of dislocation cores, where Tc variation and an enhancement of normal quasiparticle density are significant.
