摘要：

Two-dimensional arrays of micrometer-scale thin square slabs of amorphous Sm0.2Co0.8 were prepared by means of e-beam lithography and dc sputtering. When a laser beam is Bragg-diffracted by this structure, under transverse magneto-optical Kerr effect geometry, the intensities of the various diffracted beams have very different variations as a function of applied magnetic field. The diffraction hysteresis loops provided by the various Bragg-diffracted beams yield information about the average domain structure of the individual particles.
