Abstract
By simultaneous Co and Ca doping we were able to obtain an EuFe2As2-based compound with superconductivity appearing above the antiferromagnetic order of Eu2+ magnetic moments. However, as soon as the antiferromagnetic order appears, a reentrance behavior is observed—instead of zero resistivity and diamagnetic signal down to the temperature of 2 K. By investigating magnetization, ac susceptibility, and electrical transport properties of Eu0.73Ca0.27(Fe0.87Co0.13)2As2, and comparing them to previously studied Mössbauer effect and neutron scattering measurements of this and similar compounds, an explanation of such behavior is proposed.
