利用调频旋转磁场对Y2Ba4Cu7Oy(Y247)进行了三轴取向实验。尽管Y247顺磁材料的磁各向异性仅来源于二维CuO2和一维CuO链结构，但在环氧树脂的固化过程中，仍成功地获得了三轴取向较强的晶体，其取向错位角小于1.5°。我们的结果表明，在不采用熔体凝固或薄膜沉积等外延方法的情况下，可以制备三轴或双向取向的块体和厚膜，并且调制旋转磁场不仅适用于RE247化合物，而且原则上也适用于包括实际应用的REBa2Cu3Oy在内的正交结构的高临界温度铜酸盐超导体。
Tri-axial orientation of orthorhombic and twin-free Y2Ba4Cu7Oy (Y247) powders was attempted using a rotating magnetic field with modulated rate. Although magnetic anisotropy of paramagnetic Y247 originated only from the two-dimensional CuO2 and one-dimensional Cu–O chain structures are small, strong tri-axial grain orientation with misorientation angles below 1.5° was successfully achieved during the solidification process of epoxy resin. Our present results indicate the possibility of fabrication of tri- or bi-axial grain-oriented bulk and thick films without applying epitaxial methods, such as melt-solidification or thin film deposition, and that the modulated-rotation magnetic field is applicable not only to RE247 compounds but also to orthorhombic high critical temperature cuprate superconductors, including practical REBa2Cu3Oy, in principle.
