8 Apr 2005 | | Journal: | Phys. Rev. Lett. 94, 197202 (2005) | | Subject: | Strongly Correlated Electrons | cond-mat.str-el | | Affiliation: | Department of Physics, University of Liverpool, UK, SPEC, CEA Saclay, France, ILL, Grenoble, France | | Abstract: | Spin correlations in the paramagnetic phase of lanthanum cuprate have been studied using polarized neutron scattering, with two important results. First, the temperature dependence of the characteristic energy scale of the fluctuations and the amplitude of the neutron structure factor are shown to be in quantitative agreement with the predictions of the quantum non-linear sigma model. Secondly, comparison of a high-temperature series expansion of the equal-time spin correlations with the diffuse neutron intensity provides definitive experimental evidence for ring exchange. | | Source: | arXiv, cond-mat/0504204 | | Services: | Forum | Review | PDF | Favorites | |
