Magnetic field induced orientation of superconducting MgB${}_2$ crystallites determined by X-ray diffraction

J. Li, D. Vaknin, S. L. Bud'ko +5

X-ray diffraction studies of fine polycrystalline samples of MgB${}_2$ in the superconducting state reveal that crystals orient with their \emph{c}-axis in a plane normal to the dire…
