Abstract

We report on the measurements of both vertical and lateral levitation forces between a permanent magnet NdFeB and a polycrystalline YBa ₄Cu ₆O _7-δ superconductor. The analysis of the obtained results revealed an interesting correlation between the behavior of the forces in the field-cooled and zero-field-cooled regimes, resembling the structure of the so-called susceptibility spectrum χ''(χ'). Such force-force diagrams can be useful for identifying flux distribution structure inside a superconducting material.
