Temperature dependent critical current density and flux-creep measurement were carried out in magnetically aligned HgBa2Ca2Cu3Oy. For 20 K

High-Tcsuperconducting thick films were prepared using a method of combined grain shape alignment and magnetic field alignment by orthogonal alignment forces. Superconducting films with a thickness of about 100 µm exhibiting Tc(0)=91 K were successfully obtained. We confirmed the grain alignment of thick Y1Ba2Cu3O7-yand Y0.5Dy0.5Ba2Cu3O7-yfilms by means of the X-ray diffraction method. As a result, the grain alignment is produced with an increase in the heat treatment temperature and time in a magnetic field. The alignment ratio of Y0.5Dy0.5Ba2Cu3O7-y, which is Y1Ba2Cu3O7-ywith the Y-site doped with high-magnetic-moment and high-anisotropy rare earth, is higher than that of the Y1Ba2Cu3O7-y.
