Unusual superconductivity up to 49 K in single crystalline R-doped CaFe2As2 (Ca122) at ambient with R = rare earth
The discovery in 2008 of the Fe-pnictide and Fe-chalcogenide superconductors has generated immense interest. They crystallize in four different structures, namely, the 1111-phase (RFeAsO, where R = rare earth) with the ZrCuSiAs structure (P4/nmm); the 122-phase (AeFe2As2 and AFe2As2, where Ae = alka...
