Magnetic Behavior of Light Rare Earth Ions in (Nd,Eu,Gd)-123 Superconductors
The paramagnetic light-rare-earth (LRE) ions significantly participate on the total measured magnetic signal of LRE-123 superconductors. At low temperatures, most of the paramagnetic LRE ions become magnetically ordered. The ordering depends on the ions distance in the given compound. We investigated magnetic behavior of LRE ions in the (Nd0.33Eu0.38Gd0.28)Ba2Cu3O y superconductor in a broad temperature and magnetic field range with the aim to find thermodynamic characteristics of the compound. The thermodynamic reversible magnetization and the associated thermodynamic characteristics were obtained.
