Abstract

The quasi one-dimensional antiferromagnet Sr{sub 2}CuO{sub 3} exhibits Neel order of Cu{sup 2+} moments (S = 1/2) at T{sub N} = 5.41(1) K, as demonstrated by (1) almost resolution-limited magnetic Bragg reflections in neutron scattering measurements, and (2) spontaneous muon spin precession in zero-field muon spin relaxation ({mu}SR) measurements. The temperature dependence of the order parameters are consistent between the two experimental techniques. From the neutron data, the authors obtained an upper-limit for the ordered moment size of {approximately} 0.06 {mu}{sub B}. This indicates a significant moment reduction from quantum fluctuations.

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}

Muon-spin-rotation measurements in infinite-layer and infinite-chain cuprate antiferromagnets: Ca[sub 0. 86]Sr[sub 0. 14]CuO[sub 2] and Sr[sub 2]CuO[sub 3]

Journal Article Keren, A; Le, L; Luke, G; ... - Physical Review, B: Condensed Matter; (United States)

We have performed zero-field muon-spin-rotation [mu]Sr measurements of the infinite-layer'' cuprate compound Ca[sub 0.86]Sr[sub 0.14]CuO[sub 2] and the infinite chain'' system Sr[sub 2]CuO[sub 3]. A spontaneous magnetic field from the ordered Cu moments is observed below [ital T][sub [ital N]]=540[plus minus]5 K in Ca[sub 0.86]Sr[sub 0.14]CuO[sub 2]: below [ital T]=360 K, we observe muon-spin precession with a frequency [nu]([ital T][r arrow]0=16) MHz (corresponding to a local field of 1.2 kG). The precession signal is replaced by a rapid depolarization above [ital T]=360 K due to the onset of muon diffusion. The hopping rate followed an Arrhenius law, with an activationmore »« less

Muon-spin-rotation studies in single-crystal Sr sub 2 CuO sub 2 Cl sub 2

Journal Article Le, L; Luke, G; Sternlieb, B; ... - Physical Review, B: Condensed Matter; (USA)

We report zero-field muon-spin-rotation studies on single crystals of Sr{sub 2}CuO{sub 2}Cl{sub 2} between 5 and 300 K. Magnetic order below the Neel temperature is observed, and the results are compared with those of neutron diffraction measurements. The temperature dependence of the muon precession frequencies exhibits properties characteristic to two-dimensional spin-1/2 systems with a dominant Heisenberg interaction and very small anisotropy. The splitting of the muon precession frequency below 60 K indicates either a magnetic phase transition or a change in the {mu}{sup +} site. By comparing the observed static internal field with the calculated dipolar field from Cu{sup 2+}more »« less

Antiferromagnetism of La/sub 2/CuO/sub 4-//sub y/ studied by muon-spin rotation

Journal Article Uemura, Y; Kossler, W; Yu, X; ... - Phys. Rev. Lett.; (United States)

Zero-field spin precession of positive muons has been observed in the antiferromagnetic state of La/sub 2/CuO/sub 4-//sub y/. Sharp onsets of the sublattice magnetization are found at temperatures close to those of the susceptibility maxima of different specimens. The long-lived precession signal indicates a microscopically homogeneous distribution of spin density at each Cu atom below the Neel temperature. Combination of the present results and neutron-scattering studies indicates the ordered moment per Cu atom to be significantly less than 1..mu../sub B/.

Antiferromagnetism in Sr sub 2 CuO sub 2 Cl sub 2

Journal Article Vaknin, D; Sinha, S; Stassis, C; ... - Physical Review, B: Condensed Matter; (USA)

Magnetic-susceptibility {chi}({ital T}) and neutron-diffraction studies on single-crystal specimens of Sr{sub 2}CuO{sub 2}Cl{sub 2} are reported. A three-dimensional antiferromagnetic structure similar to that in La{sub 2}CuO{sub 4} is identified below the Neel temperature {ital T}{sub {ital N}}=251{plus minus}5 K by neutron diffraction, with an ordered moment {mu}(10 K)=0.34{plus minus}0.04 {mu}{sub {ital B}}/Cu aligned along the (110) crystal direction. This moment is comparable to those for La{sub 2}CuO{sub 4} samples with similar {ital T}{sub {ital N}}. No structural transition from the tetragonal {ital I}4/{ital mmm} space group is observed between 10 and 300 K. The {chi}({ital T}) near {ital T}{sub {italmore »« less
