Anomalous dynamical spin susceptibility in the SU(N) Heisenberg spin-glass model and SrCr9xGa12-9xO19
We solve the SU(N) Heisenberg spin-glass model in the limit of large N focusing on the dynamical spin susceptibility. We show that the results for the model at S = 3/2, which is appropriate for the SrCr9xGa12-9xO19 compound, have a qualitative behavior in close agreement with neutron-scattering data...

| 520 | 3 | |a We solve the SU(N) Heisenberg spin-glass model in the limit of large N focusing on the dynamical spin susceptibility. We show that the results for the model at S = 3/2, which is appropriate for the SrCr9xGa12-9xO19 compound, have a qualitative behavior in close agreement with neutron-scattering data. Quantum fluctuations produce a significant transfer of spectral weight to higher frequencies, while thermal fluctuations are responsible for a dramatic change in the low-frequency part of the dynamical spin susceptibility where T becomes comparable to the spin-glass transition temperature. © 2004 The American Physical Society. |l eng | |
