A comparative study of the formation mechanism of a single-pulse echo and its analog formed jointly by radio-frequency and two magnetic video-pulses, when their amplitude exceeds the pinning force of domain walls, is carried out. The results obtained support the assumption that the single-pulse echo signal is formed by the mechanism of local field distortions at nuclei in domain walls when they are displaced by RF pulse fronts due to the inhomogeneity of the hyperfine field and the NMR amplification factor in the domain wall
