“…where p fast/slow and Λ fast/slow are the relative weights and relaxation rates of muons implanted in two inequivalent sites, namely close to the SmO and to the FeAs planes. 20,[23][24][25][26][27] The different relaxation rates reflect the different dipolar fields created by the Sm 3+ moments at the two muon sites. LF data were fitted by keeping the p fast /p slow ratio fixed.…”

The deliberate insertion of magnetic Mn dopants in the Fe sites of the optimally-doped SmFeAsO 0.88 -F 0.12 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 transverse fields, respectively, to probe the magnetic and the superconducting order. The pure superconducting phase (at x < 0.

Monopole-limited nucleation of magnetism in Eu2Ir2O7

We present an in-depth analysis of muon-spin spectroscopy measurements of Eu 2 Ir 2 O 7 under the effect of the Eu 1-x Bi x isovalent and diamagnetic substitution as well as of external pressure. Our results evidence an anomalous correlation between the magnetic volume fraction and the order parameter only for stoichiometric Eu 2 Ir 2 O 7 , pointing towards highly unconventional properties of the magnetic phase developing therein. We argue that magnetism in Eu 2 Ir 2 O 7 develops based on the nucleation of magnetic droplets at T N , whose successive growth is limited by the need of a continuous generation of magnetic hedgehog monopoles.

We report on the magnetic properties of Eu2Ir2O7 upon the application of hydrostatic pressure P by means of macroscopic and local-probe techniques. In contrast to previously reported resistivity measurements, our dc magnetization data unambiguously demonstrate a non-monotonic P -dependence for TN , i. e., the critical transition temperature to the magnetic phase. More strikingly, we closely reproduce the recently calculated behaviour for TN under the assumption that P lowers the U/W ratio (i. e., Coulomb repulsion energy over electronic bandwidth). Zero-field muon-spin spectroscopy measurements confirm that the local magnetic configuration is only weakly perturbed by low P values, in agreement with theoretical predictions. The current results experimentally support the preservation of a 4-in/4-out ground state and, simultaneously, a departure from the single-band j eff = 1/2 model across the accessed region of the phase diagram.
