Effect of viscosity of the dispersed media on the bi-axial orientation degrees in magnetically aligned Y123 powder

We clarified the dependence of biaxial orientation degrees on the initial viscosity ( η init ) and curing time ( t cure ) of resins used for YBa 2 Cu 3 O y (Y123) powder samples aligned under the modulated rotating magnetic fields (MRFs) in two different types of resin. The biaxial orientation degrees of the magnetically aligned Y123 powder samples significantly improved when using a resin with relatively lower η init and a longer t cure within the MRF range of 0.8 – 5 T. These findings contribute to the fabrication of rare-earth-based cuprate superconductor ceramics with high biaxial orientation degrees using permanent magnets and the colloidal process.
