The Absence of Superconductivity in Single Phase CaFe2As2 under Hydrostatic Pressure
W. Yu, A. A. Aczel, T. J. Williams +4
Recent high-pressure studies found that superconductivity can be achieved under very low pressure in the parent iron arsenide compound CaFe2As2, although details of the sharpness a…
Weak quasistatic magnetism in the frustrated Kondo lattice Pr_2Ir_2O_7
D. E. MacLaughlin, Y. Ohta, Y. Machida +6
Muon spin relaxation experiments have been performed in the pyrochlore iridate Pr_2Ir_2O_7 for temperatures in the range 0.025-250 K. Kubo-Toyabe relaxation functions are observed…
Superconductivity coexisting with phase-separated static magnetic order in (Ba,K)FeAs, (Sr,Na)FeAs and CaFeAs
T. Goko, A. A. Aczel, E. Baggio-Saitovitch +22
The recent discovery and subsequent developments of FeAs-based superconductors have presented novel challenges and opportunities in the quest for superconducting mechanisms in corr…
Muon spin relaxation studies of magnetic order and superfluid density in antiferromagnetic NdOFeAs, BaFe2As2 and superconducting (Ba,K)Fe2As2
A. A. Aczel, E. Baggio-Saitovitch, S. L. Budko +15
Zero-field (ZF) muon spin relaxation (SR) measurements have revealed static commensurate magnetic order of Fe moments in NdOFeAs below K, with the ordered momen…
Itinerant spin excitations near the hidden order transition in URu2Si2
J. A. Janik, H. D. Zhou, Y. -J. Jo +12
By means of neutron scattering we show that the high-temperature precursor to the hidden order state of the heavy fermion superconductor URuSi exhibits heavily damped i…
SR studies of the frustrated quasi-2d square-lattice spin system Cu(Cl,Br)La(Nb,Ta)O: evolution from spin-gap to antiferromagnetic state
Y. J. Uemura, A. A. Aczel, Y. Ajiro +15
We report muon spin relaxation (SR) and magnetic susceptibility measurements on Cu(Cl,Br)La(Nb,Ta)O, which demonstrate: (a) the absence of static magnetism in (CuCl)…
