Muon-spin rotation measurements of the magnetic penetration depth in the iron-based superconductor Ba1xRbxFe2As2
Measurements of the magnetic penetration depth � in the Fe-based superconductor Ba1−xRbxFe2As2 (x=0.3, 0.35, 0.4) were carried out using the muon-spin rotation (�SR) technique. The temperature dependence of � is well described by a two-gap s + s-wave scenario with a small gap Δ1 � 1–3 meV and a large gap Δ2�7–9 meV. By combining the present data with those previously obtained for RbFe2As2 a dec...

متن کاملMuon spin relaxation study of LaTiO(3) and YTiO(3).
We report muon spin relaxation (μSR) measurements on two Ti(3+) containing perovskites, LaTiO(3) and YTiO(3), which display long-range magnetic order at low temperature. For both materials, oscillations in the time dependence of the muon polarization are observed which are consistent with three-dimensional magnetic order. From our data we identify two magnetically inequivalent muon stopping sit...
متن کاملA muon - spin relaxation study of BiMnO 3
We present the results of muon-spin relaxation measurements on ferromagnetic BiMnO3. Below TC = 98.0(1) K oscillations in the time-dependence of the muon polarization are observed, characteristic of a quasistatic magnetic field at a single muon site, allowing us to probe the critical behaviour associated with the magnetic phase transition. We are able to suggest candidate muon sites on the basi...
متن کاملDepth-dependent spin dynamics of canonical spin-glass films: a low-energy muon-spin-rotation study.
We have performed depth dependent muon-spin-rotation and -relaxation studies of the dynamics of single layer films of AuFe and CuMn spin glasses as a function of thickness and of its behavior as a function of distance from the vacuum interface (5-70 nm). A significant reduction in the muon-spin relaxation rate as a function of temperature with respect to the bulk material is observed when the m...
