摘要：

We consider a model in which a bilinear Hamiltonian couples an optically inactive mode (magnon) with optically active modes (phonons). The dielectric function is derived both by a classical method and by the use of linear response theory. It is shown that the low frequency dielectric constant is increased above the value which it has in the absence of interaction. © 1978.
