## Description

- description: 'The paper presents fabrication and characterization of spark plasma
    sintered textured (001) MgB2 with a record degree of orientation of about 40 %
    by ultra-sonication and slip casting in high magnetic field (12 T), compared to
    a 16 % orientation in zero-field slip casting. Structural characterization was
    performed by X-ray diffraction, and electron microscopy. The analysis revealed
    unexpected preferred orientation also in the MgO secondary phase due to the epitaxial
    growth of (111) MgO on (001) MgB2. The influence of oriented microstructure on
    the superconducting characteristics expressed by Jc, Hirr and on the pinning properties
    were assessed. High anisotropy versus sample orientation in applied magnetic field,  H,
    was observed for the critical current density, Jc, irreversibility field, Hirr,
    pinning activation energy, U*, extracted from relaxation measurements, and h0=H/Hirr
    corresponding to the maximum of the volume pinning force Fp,max. The zero-field
    critical current, Jc0 and Fp,max are weakly or not dependent on the direction
    of H, while the other indicated parameters are significantly influenced. Results
    enable control of superconducting parameters by further optimization of microstructure
    through MgB2 texturing as a novel and viable strategy for development of bulk
    MgB2 with enhanced properties when taking advantage of its anisotropy. '
