Non-Fermi Liquid Behavior Close to a Quantum Critical Point in a Ferromagnetic State without Local Moments
E. Svanidze, L. Liu, B. Frandsen +12
A quantum critical point (QCP) occurs upon chemical doping of the weak itinerant ferromagnet Sc_{3.1}In. Remarkable for a system with no local moments, the QCP is accompanied by no…
High-field spectroscopy of singlet-triplet transitions in the spin-dimer systems Sr3Cr2O8 and Ba3Cr2O8
Zhe Wang, D. Kamenskyi, O. Cépas +14
Magnetic excitations in the isostructural spin-dimer systems Sr3Cr2O8 and Ba3Cr2O8 are probed by means of high-field electron spin resonance at sub-terahertz frequencies. Three typ…
Magnetic properties of the geometrically frustrated S=1/2 antiferromagnets, La2LiMoO6 and Ba2YMoO6, with the B-site ordered double perovskite structure: Evidence for a Collective Spin Singlet Ground State
T. Aharen, J. E. Greedan, A. A. Aczel +9
Two B-site ordered double perovskites, La2LiMoO6 and Ba2YMoO6, based on the S = 1/2 ion, Mo5+, have been investigated in the context of geometric magnetic frustration. Powder neutr…
75As NMR study of single crystals of the heavily overdoped pnictide superconductors Ba{1-x}KxFe2As2 (x = 0.7 and 1)
S. W. Zhang, L. Ma, Y. D. Hou +6
We performed As NMR studies on two overdoped high-quality BaKFeAs (x=0.7 and 1.0) single crystals. In the normal states, we found a dramatic increase o…
MuSR studies of RE(O,F)FeAs (RE = La, Nd, Ce) and LaOFeP systems: possible incommensurate/stripe magnetism and superfluid density
J. P. Carlo, Y. J. Uemura, T. Goko +13
Muon spin relaxation (MuSR) measurements in iron oxy-pnictide systems have revealed: (1) commensurate long-range order in undoped LaOFeAs; (2) Bessel function line shape in La(O0.9…
Muon spin relaxation studies of incommensurate magnetism and superconductivity in stage-4 LaCuO and LaSrCuO
A. T. Savici, Y. Fudamoto, I. M. Gat +9
This paper reports muon spin relaxation (MuSR) measurements of two single crystals of the title high-Tc cuprate systems where static incommensurate magnetism and superconductivity…
Muon Spin Relaxation Study of (La, Ca)MnO3
R. H. Heffner, J. E. Sonier, D. E. MacLaughlin +5
We report predominantly zero field muon spin relaxation measurements in a series of Ca-doped LaMnO_3 compounds which includes the colossal magnetoresistive manganites. Our principa…
Muon Spin Relaxation and Nonmagnetic Kondo State in PrInAg_2
D. E. MacLaughlin, R. H. Heffner, G. J. Nieuwenhuys +7
Muon spin relaxation experiments have been carried out in the Kondo compound PrInAg_2. The zero-field muon relaxation rate is found to be independent of temperature between 0.1 and…
Muon Spin Relaxation Study of Reentrant Spin Glasses: Amorphous-Fe_{1-x}Mn_x
M. J. P. Gingras, M. Larkin, I. Mirebeau +5
We have performed an extensive muon spin relaxation study of the well known (FeMn)PBAl reentrant spin glass. We find a strong increase of the dy…
Muon-Spin Rotation Measurements of the Magnetic Field Dependence of the Vortex-Core Radius and Magnetic Penetration Depth in NbSe2
J. E. Sonier, R. F. Kiefl, J. H. Brewer +7
Muon-spin rotation spectroscopy has been used to measure the internal magnetic field distribution in NbSe2 for Hc1 << H < 0.25 Hc2. The deduced profiles of the supercurrent density…
