摘要

Gas-tight containers with the crystal hydrate K2CO3·1.5H2O and powdered YBa2Cu3O6+δ (YBCO) exhibited a puzzling sharp loss of part of their weight during and after 0.5 h of exposure to a magnetic field with a frequency of 50 MHz. A dependence of the weight loss magnitude on the oxygen content in YBCO shows a significant dip in the region where oxygen orderings exist in the basal plane. The connection of the inexplicable weight changes with the structural features of YBCO is discussed.
