24 Jul 2007 | | Abstract: | Dy2Ti2O7 is a model geometrically frustrated magnetic material with a
strongly correlated paramagnetic spin ice regime that extends from 1K down to
as low as 60 mK. We find that diffuse elastic neutron scattering intensities in
the spin ice regime can be remarkably well described by a picture of weakly
interacting hexagonal clusters, suggesting an "emergent cluster" response, as
observed in other geometrically frustrated magnets. However, using Monte Carlo
simulations, we find that an equally good description is obtained via a
microscopic theory provided that the interaction terms in the model Hamiltonian
are fine-tuned. Our results suggest a purely microscopic origin of the
cluster-like experimental scattering, which is therefore not indicative of
emergent quasiparticles. | | Source: | arXiv, 0707.3477 | | Services: | Forum | Review | PDF | Favorites | |
