YBa₂Cu₃O₇ (Y123), which has a high critical temperature around 90 K, exhibits superconductivity at liquid nitrogen temperatures. This makes it advantageous in terms of cooling costs and highly promising for practical applications. REBa₂Cu₃O₇ (RE123), where RE denotes a rare-earth element), including Y123, has a layered structure. To maintain high superconductivity across grain boundaries, alignment of the c-axis as well as orientation of the a- and b-axes is required. In this study, we attempted to align the magnetically hard axis using a rotating magnetic field and investigated the effect of varying Dy doping levels in Y123 on magnetic susceptibility anisotropy.
