Abstract

We report magnetic anisotropics (Δ χ ) depending on rare earth (RE) element in the paramagnetic REBa 2 Cu 3 O 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 |Δ χ | largely depended on y and RE elements. Especially for heavy RE elements, |Δ χ | 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.
