Comparative study of critical current density, pinning force and levitation force behavior in Yb211 doped-Sm123 bulk superconductors
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2012-04-15)The effect of Yb211 doping on the critical transition temperature (T-c), c-lattice parameter, critical current density (J(c)), volume pinning force (F-p) and the vertical levitation force density properties of MPMG-processed ... -
Comparison of levitation force relative to thickness of disk shaped YBa2Cu3O7-x prepared by MPMG and FQMG processes
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2009-11-20)The precursor YBCO in the stoichiometric ratio of 1:23 were fabricated using the melt-powder-melt-growth (MPMG) technique, and flame-quench-melt-growth (FQMG) technique. The superconducting regions were determined by ... -
Complete flux jumping in nano-structured MgB2 superconductors prepared by mechanical alloying
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2009-07-08)High density nano-crystalline MgB2 bulk superconductors with induced pinning centres were prepared from elemental precursors by a sequence of ball milling, heat treatment, and final pressing. The XRD results revealed the ... -
Levitation force at different temperatures and superconducting properties of nano-structured MgB2 superconductors
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2010-03-04)The levitation and pinning force properties of nanocrystalline MgB2 superconductors prepared by a mechanical alloying technique with varying milling duration have been investigated. Levitation force measurements under ...
