Orientation degrees in Dy123 powders by using Linear-drive type Modulated Rotating Magnetic Field system

Abstract

Bi-axial magnetic alignment of DyBa2Cu3Oy (y ~ 7) grains with high in-plane orientation degrees has been achieved using only permanent magnets as magnetic field sources. When compared to electromagnets such as a superconducting magnet, arrayed magnets offer a lower cost and greater versatility as magnetic field sources for magnetic alignment. In this study, permanent magnets were arranged in such a way that they were able to create a rotating magnetic field with a strength of 0.8 T-class. This helps with the magnetic alignment of functional materials like cuprate superconductors.
