Аннотация
Measurements of the magnetostriction of the isotropic high-temperature superconductor Ba0.66K0.34BiO3 revealed an effect of the order of 10−6 which exceeds that for conventional superconductors but is not as high as the giant magnetostriction of cuprate high-temperature superconductors. A thermodynamic analysis of the results enables comparison with the results of numerical calculations of effects induced by magnetic flux pinning.
