Summary

PINNED TYPE II SUPERCONDUCTORS CAN REPEL MAGNETIC FIELDS DUE TO FLUX PINNING. THE RECENTLY DEVELOPED MPMG PROCESS ENABLED THE AUTHORS TO INTRODUCE FINE NON-SUPERCONDUCTING PARTICLES INTO YBCO MATRIX AND TO ACHIEVE LARGE FLUX PINNING FORCE. IT WAS FOUND THAT AN ADDITION OF SILVER WAS EFFECTIVE FOR REDUCING THE AMOUNT OF CRACKING AND FOR INCREASING THE REPULSIVE FORCE OF THE SUPERCONDUCTORS AGAINST MAGNETS. A HEAVY OBJECT WAS LEVITATED ABOVE THE MPMG GROWN YBCO SILVER COOLED WITH LIQUID NITROGEN. THE AUTHORS ALSO SUCCEEDED IN LEVITATING A PERSON.
