Abstract
There were investigated the adsorptional properties of the superconduc ting powder of yttrium ceramics YBa2Cu3O7-delta in external magnetic f ield in the region of temperatures of superconducting transition. Argo n and oxygen were as adsorbates. Oxygen adsorption was found to be abn ormal. The specific surface of the superconducting adsorbent for oxyge n appeared to depend dramatically on temperature and magnitude of the external magnetic field. These phenomena seem to be connected with the repulsion of paramagnetic oxygen molecules from diamagnetic surface o f the adsorbent.
