Magnetization measurements of single levitated grains of Ba2YCu3O7

Description

An electrodynamic balance has been constructed in which the perturbative forces from applied magnetic fields are used to probe the superconducting properties of single levitated charged grains of high T/sub c/ superconductors with diameters approx. <10 μm. The low-temperature magnetization of selected Ba2YCu3O7 grains has been observed to exhibit a flux exclusion near 80% of the theoretical maximum. Hysteresis, flux creep, and the lower critical field are identified
