Abstract :We investigated the microstructure and magnetic properties of Gd123:Gd211 = 1-y : y insert ignore into journalissuearticles values(y = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5); bulk superconductors with the diameter of 13 mm and thickness of 5 mm fabricated by melt-textured method.  The vertical levitation force between melt-textured bulk superconductors and a permanent magnet is measured at 30, 40, 50, 60, and 77 K under zero-field-cooling insert ignore into journalissuearticles values(ZFC); and field-cooling insert ignore into journalissuearticles values(FC); regimes by Magnetic Levitation Force Measurement System insert ignore into journalissuearticles values(MLFMS);. The phase and microstructures properties of all samples are determined by SEM insert ignore into journalissuearticles values(Scanning Electron Microscope);. The measurements of superconducting characteristics showed that the maximum vertical levitation forces of the Gd01 sample were noted as 3.04, 2.30, 1.53, 0.91 and 0.16 N at the temperatures of 30, 40, 50, 60 and 77 K, respectively. The present results perform that a high-performance good-quality GdBCO can improve from laboratory conditions to technological applications for large scale levitated system.
