摘要：

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. The combination of a large Jcvalue and large shielding current loop is the source of such a large levitation force. © 1990 IOP Publishing Ltd.
