Previous research has found that the pairing symmetry in the iron-based superconductor Ba1-xKxFe2As2 changes from nodeless s-wave near optimally doped, x≈0.4-0.55 and Tc>30 K, to nodal (either d-wave or s-wave) at the pure endpoint, x=1 and Tc<4 K. Intense theoretical interest has been focused on this possibility of changing pairing symmetry, where in the transition region both order parameters would be present and time reversal symmetry would be broken. Here we report specific heat…

Orbital and Pauli limiting effects in heavily doped Ba0.05K0.95Fe2As2
We investigated the thermodynamic properties of the Fe-based lightly disordered superconductor Ba0.05K0.95Fe2As2 in external magnetic field H applied along the FeAs layers (H ||ab planes). The
Disentangling superconducting and magnetic orders in NaFe1−xNixAs using muon spin rotation
Muon spin rotation and relaxation studies have been performed on a "111" family of iron-based superconductors NaFe_1-xNi_xAs. Static magnetic order was characterized by obtaining the temperature and
A multiband Eliashberg-approach to iron-based superconductors
Since the discovery of the Fe-based superconductors (FeSC) a lot of efforts has been applied to elucidate the microscopic mechanism behind cooper pairing and the symmetry of the order parameter.
Thermodynamic properties of Mercury based cuprate due to Cooper pair-electron interaction
Interaction between electrons at the critical temperature that culminates into formation of Cooper pair holds the key in explaining cuprates high temperature superconductivity. We study the effects
