Bose-Einstein Condensation of Triplons in Ba3Cr2O8
A. A. Aczel, Y. Kohama, M. Jaime +5
By performing heat capacity, magnetocaloric effect, torque magnetometry and force magnetometry measurements up to 33 T, we have mapped out the T-H phase diagram of the S = 1/2 spin…
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…
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…
Absence of time reversal symmetry breaking in La_{2-x}Sr_{x}CuO_{4}
G. J. MacDougall, A. A. Aczel, J. P. Carlo +6
We have performed zero-field muon spin rotation measurements on single crystals of La_{2-x}Sr_{x}CuO_{4} to search for spontaneous currents in the pseudo-gap state. By comparing me…
Impurity-induced singlet breaking in SrCu2(BO3)2
A. A. Aczel, G. J. MacDougall, J. A. Rodriguez +8
We have performed SR studies on single crystals of SrCu(BO), a quasi-two-dimensional spin system with a spin singlet ground state. We observe two different muon site…
