Critical spin dynamics of EuO

Creators

Description

The standard coupled-mode theory of spin dynamics is evaluated for an isotropic, Heisenberg model of EuO at the critical temperature. The predicted long wavelength limit of the spin relaxation function is approximately a gaussian function of time in the time interval probed in recent neutron spin echo measurements. This functional form is distinctly different from the observed, almost exponential, decay. (author)
