摘要
We have investigated the magnetic properties of a dot array that contains two nonidentical dots per unit cell. As expected, this structure produces a diffraction pattern consisting of intense and weak spots that results from in- and out-of-phase contributions of the two sublattices. A comparison of the magneto-optical Kerr measurements on the weak and strong diffraction spots enables the switching of the two sublattices to be determined independently.
