Decrease in the intrinsic microwave loss of YBa2Cu3O6.95 by Zn doping

Measurements of the microwave surface resistance of single crystals of YBa2(Cu1−xZnx)3O6.95 at 3.8 and 34.8 GHz have been performed with zinc contents of x=0, 0.0015, and 0.0031. The microwave loss in the superconducting state decreases when zinc impurities are added, demonstrating that some defects...

Beschreibung
Zusammenfassung:	Measurements of the microwave surface resistance of single crystals of YBa2(Cu1−xZnx)3O6.95 at 3.8 and 34.8 GHz have been performed with zinc contents of x=0, 0.0015, and 0.0031. The microwave loss in the superconducting state decreases when zinc impurities are added, demonstrating that some defects are required to achieve state-of-the-art surface resistance in this material.
