Effect of the external pressure at the crossover between magnetism and superconductivity in LnFeAsO1-x Fx (Ln = La0.7Y0.3, Ce) superconductors

Sanna, S. Prando, G. Khasanov, R.

The interplay between magnetism and superconductivity is tuned as a function of the external pressure in LnFeAsO1-xFx at x values close to the appearance of superconductivity for lanthanide ion Ln=La0.7Y0.3 and Ce. The results show that in these compounds, both superconductivity and magnetism are reinforced by pressure. Furthermore, muon spin...

Role of magnetic dopants in the phase diagram of Sm 1111 pnictides: The case of Mn

Lamura, G. Shiroka, T. Bordignon, S.

The deliberate insertion of magnetic Mn dopants in the Fe sites of the optimally doped SmFeAsO0.88F0.12 iron-based superconductor can modify in a controlled way its electronic properties. The resulting phase diagram was investigated across a wide range of manganese contents (x) by means of muon-spin spectroscopy (μSR), both in zero and in...
