The influence of laser irradiation spacing on the shape of the so-called “saw-tooth” domains is reported. Dynamic behavior under an external field, applied in the rolling direction, is investigated using a suitable imaging package developed for magneto-optical Kerr effect studies. Results relative to irradiated and non-irradiated commercial Hi–B specimens are confronted and the incidence on core losses is discussed.
