In this paper, the following ferro magnetic chain equation with periodic initial value problem is considered:The seni-discrete and fully discrete Fourier spectral and pseudo-spectral schemes are proposed. The convergences and stabilities for the schemes are proved. More over, the algorithm for the pseudo-spectral method is provided. Finally, some numerical experiments are given and compared with difference methods.
