Abstract

We report magnetic anisotropics (Δχ) depending on rare earth (RE) element in the paramagnetic REBa2Cu3O y (RE123) system as an important finding of magneto-scientific grain-orientation. The c-axis-oriented RE123 powder samples using static or rotating magnetic fields were fabricated at room temperature to clarify Ax. Their easy axes of magnetization were mainly dominated by second-order Stevens factors, whereas |Δχ| largely depended on y and RE elements. Especially for heavy RE elements, |Δχ| reached the order of 10-4, indicating that appropriate choice of RE directly leads to a drastic reduction of required magnetic fields for grain-orientation of RE123.
