E. Podkletnov and R. Nieminen Tampere University of Technology, Institute ofMaterials Science, P.O. Box 589, SF-33101 Tampere, Finland Received 9 September 1992 Revised manuscript received October, 13, 1992
Shielding properties of single-phase dense bulk superconducting ceramics of YBa,Cu,O,_, against the gravitational force were studied at temperatures below 77 K. A small non-conducting and non-magnetic sample weighing 5.48 g was placed over a levitating superconducting disk and the loss of weight was measured with high precision using an electro-optical balance system. The sample was found to lose from 0.05 to 0.3% of its weight, depending on the rotation speed of the superconducting disk. Partial loss of weight might be the result of a certain state of energy which exists inside the crystal structure of the superconductor at low temperatures. The unusual state of energy might have changed a regular interaction between electromagnetic, nuclear and gravi-tational forces inside a solid body and is responsible for the gravity shielding effects
