Anomalous ferromagnetic behaviour of Y₂O₃ and CuO nanoparticles in YBa₂Cu₃Oy superconductor

Abstract:

Anomalous ferromagnetic behaviour of the Y₂O₃ and CuO components in YBa₂Cu₃O[subscript y] (Y123) was observed after severe reduction of particle size. The particle size reduction was performed in two ways. First, Y₂O₃, BaCO₃ and CuO were ground for different times to reduce the particle size to the nanoscale. It was found that the superconducting phase could not be obtained without heat treatment, but a weak ferromagnetic behaviour of the mixture was observed at liquid and room temperatures. ...
