摘要：
Magnon Raman spectra in the half-filled two-dimensional Hubbard model are calculated by using the exact diagonalization of a square-root 8 x square-root 8 lattice. Theoretical results of the peak positions and relative intensities of the B1, A1 and B2 spectra agree with the observed ones. The frequency dependence of the spectra on the incident light is discussed.
