MAGNETIC HIGH T-C SUPERCONDUCTING LIKE BEHAVIOR OF BETA-, BETA''- AND GAMMA-ALUMINA

摘要

beta,beta '' and gamma-Al2O3 samples were synthesized. The temperature dependence of the magnetic susceptibility has anomalous diamagnetic-paramagnetic transitions, like Meissner effect, around 80 K, and consequently high T-c superconducting like magnetic behavior. [References: 4]
