Effect of Ag nanoparticles as flux pinning centers in YBa2Cu3O7-δ
The objective of this work is to investigate the effect of Ag nanoparticles as the flux pinning centers. Ag nanoparticles with different particle sizes from 30 to 1000 nm were prepared through the chemical reduction of AgNO3 in an alcohol solution. Then, samples of YBa2Cu3O7-δ superconductors were...
