Mechanical Method for Experimental Determination of the First-Penetration Field in High-Temperature Superconductors

In this paper, we propose a mechanical method to determine the first-penetration field Hp , in a bulk of a high-temperature superconductor. It consists in comparing measurement and numerical calculation of forces exerted between a magnet and the superconductor. The deviations between the measured fo...
