Abstract:
To produce polycrystalline superconductor ceramics with potentially higher critical currents by eliminating grain boundary weak links caused by grain orientation misfit, we use a method combining grain shape alignment and magnetic field alignment by orthogonal alignment forces. Continuing this work, we report here X-ray diffraction data demonstrating the first preparation of an ∼80µm thick Bi 2 Sr 2 Ca 0.7 Yb 0.3 Cu 2 O x film having substantial biaxial grain alignment; a very high degree of c -axis alignment is combined with 〉 30% preferential 〈 100 〉 axis alignment within the a - b plane (relative to a random 〈 100 〉 axis distribution in that plane). While films with this composition are not good superconductors, they demonstrate the feasibility of the method.
