TL;DR: This work identifies an experimental situation in which the measured response is dominated by an effect resulting from the muon-induced local distortion rather than the intrinsic behavior of the host compound.

TL;DR: In this article, it was shown that the newly discovered Fe-based superconductor displays multigap superconductivity with line nodes, where the gap structure is drastically altered upon replacing one of the spacer layers, indicating the need to understand how the pairing state is tuned by changes of the asymmetry between the pnictogens located either side of the Fe planes.

TL;DR: In this paper, the results of a muon-spin rotation were reported to determine the superconducting ground state of the iron-based superconductor with a value for the in-plane penetration depth of approximately 28.28m.

TL;DR: The preparation of La2SrCr2O7F2 demonstrates that low-temperature topochemical reactions offer an alternative synthesis route to materials of this type, and the structure-property relations of this phase and other Cr(4+) oxide phases are discussed.

TL;DR: The synthesis of the first 4d transition metal oxide-hydride, LaSr3 NiRuO4 H4 , is prepared via topochemical anion exchange and the observed weak inter-cation magnetic coupling can be attributed to poor overlap between Ni 3dz2 and H 1s in the super-exchange pathways.
