摘要: We have studied the microstructural and superconducting properties of YBa2Cu3O7 films fabricated by pulsed laser evaporation YBa2Cu3O7‐Ag targets, containing approximately 30% weight silver. The produced excimer evaporation/ablation targets were found to possess better than prepared under same conditions from bulk targets. deposited on yttria stabilized zirconia (YSZ) substrates at 650 °C showed helium ion channeling yields 9%–12%, while had in range 18%–25%. critical current density YBa2Cu3O7Agx YSZ values 1.8×106 A/cm2 77 K which corresponds an 80% improvement obtained cold pressed Based structural chemical information, it appears that two ...
