摘要：

Normal-state orbital diamagnetism of charged bosons quantitatively accounts for recent high-resolution magnetometery results near and above the resistive critical temperature T-c of superconducting cuprates. The parameter-free descriptions of normal-state diamagnetism, T-c, upper critical fields, and specific heat anomalies support the 3D Bose-Einstein condensation of preformed real-space pairs with a zero off-diagonal order parameter above T-c at variance with phase fluctuation scenarios of cuprates.
