Enhancement of magneto-optical properties of a magnetic grating

초록

The magneto-optical properties of one-dimensional magnetic grating structure of Co2MnSi film were investigated. By using the interference pattern of two femtosecond laser beams, a selective-area annealing of as-deposited Co2MnSi film was achieved and one-dimensional magnetic grating structures were fabricated. The longitudinal Kerr rotations of the zeroth- and the first-order diffracted beams were measured. The longitudinal Kerr rotation of the first-order diffracted beam is nearly 18 times larger than that of the zeroth-order beam.
