Synthetic procedure from Colin Greaves, "Structural,
Electrical and Magnetic Properties of Perovskite Ceramics," in Inorganic
Experiments, edited by J. Derek Woolins, Wiley-VCH, 1994, pages 265-270
The magnetic flux of a magnet will not penetrate
a superconducting material, enabling a magnet to be levitated on a superconducting
material. In this experiment a pellet of YBa2Cu3Ox
is prepared and cooled to its superconducting state in liquid nitrogen. See
