Abstract
Many compounds based on planes (cuprates) superconduct below a critical temperature Some of them show a second phase where a spontaneous static magnetic field appears below a critical temperature which is lower than By comparing and in numerous superconducting families, each with its own maximum we find that the same energy scale determines both critical temperatures. This clearly indicates that the origin of superconductivity in the cuprates is magnetic.
