Out-of-equilibrium behavior of coarsening ferromagnets

The out-of-equilibrium properties of ferromagnets quenched below the critical point are discussed in the dynamical scaling limit. The autoresponse and the autocorrelation are studied for both perfect and disordered ferromagnets. The scaling functions of the autoresponse are found to be in agreement with the predictions coming from the theory of local scale-invariance. Large finite time corrections to the scaling behavior of the autocorrelation are revealed for the disordered magnets.
