Description:
X-ray diffraction patterns of superconducting YBa2Cu3O(7-x) particles which have typical dimensions D of less than 5 microns and do not levitate in an inhomogeneous magnetic field at T less than Tc show marked evidence of particle alignment when powder specimens are subjected to a 0.5-T field at T less than Tc, but reveal random orientation for T greater than Tc. A majority of the particles align preferentially with their antiphase twin boundary planes and a-b planes along the applied field, but a minority align with their b axes along the field.
