A time-resolution study with a plastic scintillator read out by a Geiger-mode Avalanche Photodiode
A. Stoykov, R. Scheuermann, K. Sedlak
In this work we attempt to establish the best time resolution attainable with a scintillation counter consisting of a plastic scintillator read out by a Geiger-mode Avalanche Photo…
Quantum magnetism in molecular spin ladders probed with muon-spin spectroscopy
T. Lancaster, F. Xiao, B. M. Huddart +10
We present the results of muon-spin spectroscopy (SR) measurements on the molecular spin ladder system (Hpip)CuBrCl, [Hpip=(CHN)]. Usin…
Direct spectroscopic observation of a shallow hydrogen-like donor state in insulating SrTiO
Z. Salman, T. Prokscha, A. Amato +4
We present a direct spectroscopic observation of a shallow hydrogen-like muonium state in SrTiO which confirms the theoretical prediction that interstitial hydrogen may act as…
Probing the magnetic ground state of the molecular Dysprosium triangle
Z. Salman, S. R. Giblin, Y. Lan +4
We present zero field muon spin lattice relaxation measurements of a Dysprosium triangle molecular magnet. The local magnetic fields sensed by the implanted muons indicate the coex…
Close proximity of FeSe to a magnetic quantum critical point as revealed by high-resolution SR measurements
V. Grinenko, R. Sarkar, P. Materne +12
A nematic transition preceding a long-range spin density wave antiferromagnetic phase is a common feature of many Fe based superconductors. However, in the FeSe system with a nemat…
Behaviour of a muonic atom as an acceptor centre in diamond
T. N. Mamedov, A. S. Baturin, K. I. Gritsaj +5
Polarized negative muons were used to study the behaviour of the boron acceptor centre in synthetic diamond produced by the chemical vapour deposition (CVD) method. The negative mu…
The 10 Tesla muSR instrument: detector solutions
A. Stoykov, R. Scheuermann, K. Sedlak +3
Solutions to the detector system of the High-Field muSR instrument at the Paul Scherrer Institut (PSI) in Switzerland are presented. The strict technical requirements are fulfilled…
Field-induced electronic phase separation in the high-temperature superconductor LaSrCuO
S. Holm-Dahlin, J. Larsen, H. Jacobsen +14
We present a combined neutron diffraction and high field muon spin rotation (SR) study of the magnetically ordered and superconducting phases of the high-temperature supercondu…
Behaviour of muonium in synthetic diamond
T. N. Mamedov, V. D. Blank, V. N. Gorelkin +7
The probabilities of finding the muon in various states in synthetic single crystal and polycrystalline diamond were studied. In the IIa-type single-crystal sample at 150 K the con…
Photo-induced persistent inversion of germanium in a 200-nm-deep surface region
T. Prokscha, K. H. Chow, E. Stilp +6
The controlled manipulation of the charge carrier concentration in nanometer thin layers is the basis of current semiconductor technology and of fundamental importance for device a…
The new versatile general purpose surface-muon instrument (GPS) based on silicon photomultipliers for SR measurements on a continuous-wave beam
A. Amato, H. Luetkens, K. Sedlak +5
We report on the design and commissioning of a new spectrometer for muon-spin relaxation/rotation studies installed at the Swiss Muon Source (SS) of the Paul Scherrer Institute…
On the robustness of the MnSi magnetic structure determined by muon spin rotation
P. Dalmas de Reotier, A. Yaouanc, A. Amato +6
Muon spin rotation (muSR) spectra recorded for manganese silicide MnSi and interpreted in terms of a quantitative analysis constrained by symmetry arguments were recently published…
A lens-coupled scintillation counter in cryogenic environment
A. Stoykov, R. Scheuermann, A. Amato +4
In this work we present an elegant solution for a scintillation counter to be integrated into a cryogenic system. Its distinguishing feature is the absence of a continuous light gu…
