Abstract

Inelastic-neutron-scattering experiments on Yb{sub 4}As{sub 3} revealed the existence of low-energy spin excitations, which are characteristic of a one-dimensional Heisenberg-type antiferromagnetic coupling at low temperatures where charge ordering takes place. Superimposed on the one-dimensional spin excitations, an unusual magnetic response is also observed around the one-dimensional zone center. These results strongly suggest that the heavy-electron behavior in Yb{sub 4}As{sub 3} is a unique phenomenon caused by charge ordering; it results from the fact that the compound contains doped one-dimensional 4f{sup 1} hole chains with strong on-site f-electron correlations. {copyright} {ital 1997} {ital The American Physical Society}

High-field magnetotransport in microstructures of the frustrated antiferromagnet Yb₂Pt₂Pb

Technical Report Helm, T.; Moll, P.; Chan, Mun; ...

Frustrated quantum magnets exhibit a rich variety of non-trivial quantum ground states due to their remnant entropy at zero temperature. Most studied materials are insulators, with magnetic coupling of localized spins mediated by exchange interactions. Yb₂Pt₂Pb (YPP) is a rare example of a metallic frustrated quantum magnet, where Yb³⁺ J=7/2 moments are arranged in dimers forming a Shastry-Sutherland lattice. In addition, the itinerant charge carriers of the metal provide gapless excitations able to mediate magnetic interactions (RKKY) as well as hybridize with the 4f-states, which has been proposed to lead to a novel charge-orbital separation. YPP orders antiferromagnetically (AFM) belowmore »« less

Crystal fields, disorder, and antiferromagnetic short-range order in (Yb{sub 0.24}Sn{sub 0.76})Ru

Journal Article Klimczuk, T; Wang, C; Lawrence, J; ... - Physical Review. B, Condensed Matter and Materials Physics

We report extensive measurements on a new compound (Yb{sub 0.24}Sn{sub 0.76})Ru that crystallizes in the cubic CsCl structure. Valence band photoemission and L{sub 3} x-ray absorption show no divalent component in the 4f configuration of Yb. Inelastic neutron scattering (INS) indicates that the eight-fold degenerate J-multiplet of Yb{sup 3+} is split by the crystalline electric field (CEF) into a Γ{sub 7} doublet ground state and a Γ{sub 8} quartet at an excitation energy 20 meV. The magnetic susceptibility can be fit very well by this CEF scheme under the assumption that a Γ{sub 6} excited state resides at 32 meV;more »« less

Orbital-exchange and fractional quantum number excitations in an f-electron metal, Yb ₂ Pt ₂ Pb

Journal Article Wu, L.; Gannon, W.; Zaliznyak, I.; ... - Science

Exotic quantum states and fractionalized magnetic excitations, such as spinons in one-dimensional chains, are generally expected to occur in 3d transition metal systems with spin 1/2. Our neutron-scattering experiments on the 4f-electron metal Yb₂Pt₂Pb overturn this conventional wisdom. We observe broad magnetic continuum dispersing in only one direction, which indicates that the underlying elementary excitations are spinons carrying fractional spin-1/2. These spinons are the emergent quantum dynamics of the anisotropic, orbital-dominated Yb moments. Owing to their unusual origin, only longitudinal spin fluctuations are measurable, whereas the transverse excitations such as spin waves are virtually invisible to magnetic neutron scattering.

Magnetotransport of the low-carrier density one dimensional S=1/2 antiferromagnet Yb₄A5₃.

Conference Aoki, Hideki; Cichorek, T; Custers, J; ...

The transport properties of the semimetallic quasi-onedimensional S= 1/2 antiferromagnet Yb,As, have been studied by performing low-temperature (T 2 0.02 K) and high magnetic field (B I 60 T) measurements of the electrical resistivity p(T,B). For T 2 2 K a 'heavy fermion' like behavior AAT = AT' with huge and nearly field-independent coefficient A 3 3UuRcmK' is observed, whereas at lower temperatures p(r) deviates from this behavior and slightly increases to the lowest T. In B 0 and T L 6 K the resistivity shows an anomalous magnetic-history dependence together with an unusual relaxation behavior. In tht isothermal resistivitymore »« less

Reduction of Ordered Moment and N{acute e}el Temperature of Quasi-One-Dimensional Antiferromagnets Sr{sub 2}CuO{sub 3} and Ca{sub 2}CuO{sub 3}

Journal Article Kojima, K; Fudamoto, Y; Larkin, M; ... - Physical Review Letters

We report elastic neutron diffraction and muon spin relaxation ({mu}SR) measurements of the quasi-one-dimensional antiferromagnets Sr{sub 2}CuO{sub 3} and Ca{sub 2}CuO{sub 3}, which have extraordinarily reduced T{sub N}/J ratios. We observe almost resolution-limited antiferromagnetic Bragg reflections in Sr{sub 2}CuO{sub 3} and obtain a reduced ordered moment size of {approximately}0.06{mu}{sub B}. We find that the ratio of ordered moment size {mu}(Ca{sub 2}CuO{sub 3})/{mu}(Sr{sub 2}CuO{sub 3})=1.5(1) roughly scales with their N{acute e}el temperatures, which suggests that the ordered moment size of quasi-one-dimensional antiferromagnets decreases continuously in the limit of vanishing interchain interactions. {copyright} {ital 1997} {ital The American Physical Society}
