Abstract

Easy axes of magnetization at room temperature in REBa₂Cu ₃O_y (RE: rare earth) and Bi₂Sr ₂Ca_1-xRE_xCu₂O_ywere clarified using their powders oriented in a static magnetic field. The easy axes clearly depended on the type of RE which could be mainly explained in terms of second-order Stevens factors and magnetic anisotropy of the plane. Furthermore, we found the difference in magnetic effects of Er₃₊ for orientation through systematic evaluations of Er-doped Y123 and Bi2212 powders. This result means that magnetic anisotropies of RE₃₊ ions are sensitive to not only the type of RE but also local structure of oxygen ions surrounding RE ₃₊ions
