We present measurements of the microwave complex surface impedance at 47.7 GHz in YBa2Cu3O7-δ(YBCO) films deposited by pulsed laser deposition with the explicit goal to introduce BaZrO3(BZO) nanoinclusions. Composite targets obtained by addition of BZO powder in molar percents ranging from 2.5 to 7 mol.% have been prepared and characterized. Measurements of the microwave surface impedance indicate a broadened transition in zero field, however compensated by a very large pinning frequency, indicating that while intergrain properties are still to be optimized the effect of nanometric inclusions substantially enhances the intragrain vortex pinning. © 2007 Elsevier B.V.
