Suppression of the magnetic order in CeFeAsO: non-equivalence of hydrostatic and chemical pressure
Philipp Materne, Wenli Bi, Esen Ercan Alp +12
We present a detailed investigation of the electronic properties of CeFeAsO under chemical (As by P substitution) and hydrostatic pressure by means of in-house and synchrotron Möss…
Magnetic order and spin dynamics across a ferromagnetic quantum critical point: SR investigations of YbNi(PAs)
R. Sarkar, J. Spehling, P. Materne +5
In the quasi-1D heavy-fermion system YbNi(PAs) the presence of a ferromagnetic (FM) quantum critical point (QCP) at with unconventional quan…
Structural and electronic phase diagrams of CeFeAsO1-xFx and SmFeAsO1-xFx
Hemke Maeter, Jorge Enrique Hamann Borrero, Til Goltz +17
We have studied the structural and electronic phase diagrams of CeFeAsO1-xFx and SmFeAsO1-xFx by a detailed analysis of muon spin relaxation experiments, synchrotron X-ray diffract…
Avoided ferromagnetic quantum critical point: Unusual short-range ordered state in CeFePO
S. Lausberg, J. Spehling, A. Steppke +9
Cerium 4f electronic spin dynamics in single crystals of the heavy-fermion system CeFePO is studied by means of ac-susceptibility, specific heat and muon-spin relaxation (SR). S…
Ferromagnetism and superconductivity in P-doped CeFeAsO
A. Jesche, T. Förster, J. Spehling +10
We report on superconductivity in CeFeAs1-xPxO and the possible coexistence with Ce- ferromagnetism (FM) in a small homogeneity range around x = 30% with ordering temperatures of T…
Magnetic order and spin dynamics in the proximity of a ferromagnetic quantum critical point: A μSR study of YbNi4P2
J. Spehling, M. Günther, C. Krellner +5
The local 4f-electronic spin dynamics and magnetic order in YbNi4P2 were studied by means of muon-spin relaxation measurements. Zero-field muon-spin relaxation proves static magnet…
Field-induced coupled superconductivity and spin density wave order in the Heavy Fermion compound CeCoIn5
J. Spehling, R. H. Heffner, J. E. Sonier +8
The high field superconducting state in CeCoIn5 has been studied by transverse field muon spin rotation measurements with an applied field parallel to the crystallographic c-axis c…
