Sr Substitution Effect on Ca Site for 32522-Type Ca₃Al₂O_5-yFe₂As₂ Superconductor

Abstract:

We have prepared multi-layered iron-based 32522-type (Ca, Sr)₃Al₂O_5-yFe₂As₂ superconductor with the double perovskite-based “325” structure using high-pressure technique. In this paper, we have investigated iso-valent cation Sr substitution effect on Ca site for 32522-type (Ca, Sr)₃Al₂O_5-yFe₂As₂. By the Sr atom substitution for Ca site, superconducting transition temperature (T_c) was slightly increasing, the critical current density (J_c) was kept under magnetic field near T_c and the irreversibility field (H_irr) value was also increasing.
