摘要：

In a Friedmann-Robertson-Walker (FRW) cosmological model with zero spatial curvature, we consider the interaction of the gravitational waves with the plasma in the presence of a weak magnetic field. Using the relativistic hydromagnetic equations, it is verified that large-amplitude magnetosonic waves are excited, assuming that both the gravitational field and the weak magnetic field do not break the homogeneity and isotropy of the considered FRW spacetime.
