TLDR
In this paper, the authors present results of a comprehensive study, both theoretical and experimental, of an "electromaglev" system, in which a high-temperature superconducting bulk sample, e.g. YBa 2 Cu 3 O 7 − δ (YBCO), is levitated stably in a DC magnetic field generated by electromagnets placed underneath the floating object.About:

Levitation characteristics in an HTS maglev launch assist test vehicle
TL;DR: In this paper, a permanent magnet-high temperature superconductor (PM-HTS) interaction maglev system for the Maglifter is presented, which consists of a cryostat with multi-block YBaCuO bulks and a flux-collecting PM guideway.

Superconducting Joint of Y-Ba-Cu-O superconductors using Er-Ba-Cu-O solder
TL;DR: In this article, two melt-textured Y-Ba-Cu-O superconductor blocks were successfully welded with Er−Ba-cu-O solder having a lower per-itectic temperature than that of Y−Ba−Cu−O, indicating that the two superconductors were strongly connected with this method.

TL;DR: An extremely large levitation force of as high as 30 N at a height of 1 mm was achieved in Ag-doped YBaCuO fabricated by the Melt-Powder-Melt-Growth process using a repulsive force against a 0.4 T rare-earth magnet at 77 K as discussed by the authors.

Dynamic magnetic forces in superconducting ceramics
TL;DR: In this article, the magnetic damping is inversely related to the magnet-superconductor distance and can critically damp the oscillations at small gaps, which is not correlated with the static hysteretic forces.

Magnetic field controlled levitation and suspension of a magnet above and below type II superconductors
TL;DR: In this paper, it has been found that a continuous range of distances exists where stable levitation and suspension may be obtained, and that the orientation of magnetic moment of the levitated or suspended magnet is also adjustable over a range of angles.
