Abstract

We investigated the microstructure and magnetic
properties of Gd123:Gd211 = 1-y : y (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 (ZFC) and
field-cooling (FC) regimes by Magnetic Levitation Force Measurement System
(MLFMS). The phase and microstructures properties of all samples are determined
by SEM (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.
