摘要：
Bulk YBa2Cu3O7 samples were prepared by PMP method. Through adjusting ingredients and preparation procedures, a pellet with 3.5 cm in diameter and 0.9 cm in thickness was synthesized. A mass of 1.3 kg on a magnet can be levitated at about 1 mm height at 77 K. The XRD and SEM indicate that magnetic lifting property can be enhanced by the addition of Ag2O and Y2BaCuO5.
