Gradual destruction of magnetism in the superconducting family NaFe1-xCoxAs

Abstract:

The interplay and coexistence of superconducting, magnetic, and structural order parameters in NaFe 1-xCo xAs have been studied using superconducting quantum interference device magnetometry, muon spin rotation, and synchrotron x-ray powder diffraction. Substituting Fe by Co weakens the ordered magnetic state through both a suppression of T N and a reduction in the size of the ordered moment. Upon further substitution of Fe by Co the high sensitivity of the muon as a local magnetic probe reve...
