Summary

In our report, we present new results on investigation of the influence of temperature on the levitation force between the stacks of high temperature superconducting tapes (or coated conductor - CC tapes) and a permanent magnets. We studied the changing in value of levitation force at decreasing of temperature down to 30 K for field cooled (FC) and zero field cooled (ZFC) modes for various number of tape in the stack. In the measurements we used 12 mm wide commercially available CC-tape manufactured by SuperOx. The tapes were cut into pieces 12 mm x 12 mm. The number of layers in the stack ranged from 5 to 100. Cooling of the
CC-tapes stack was carried out in cryo-free cryostat. Temperature range was from 30 to 80 K. Results showed that temperature has much influence on levitation force in ZFC mode whereas for FC mode the influence of temperature on levitation force is insignificant. The experimental data were compared with the results of calculations performed by using COMSOL Multiphysics. The obtained results are very useful for the practical application in magnetic levitation based systems.
