Feasibility of studying the dynamics of three-spin correlations in ferromagnets above Tc by the method of pseudorandom modulation of neutron polarization
Gukasov A. G., Okorokov A. I., Fuzhara F., Sherp O.
The energy spectra of triple-spin correlations in Fe are observed experimentally above Tc in a weak magnetic field. The data obtained agree with the predictions of the hypothesis of dynamic similarity for triple-spin Green's function Gi3} (ω).
