An analogue of the single-pulse echo signal in lithium ferrite is obtained under the combined influence of the trailing edge of a sufficiently long exciting radio frequency pulse and a preceding supplementary magnetic video pulse. The echo signal arises as a result of displacement of domain walls under the action of a magnetic video pulse with the amplitude exceeding the pinning force of the domain walls. This leads to an abrupt change in the direction of the effective field acting on the nuclei of the domain walls in the rotating coordinate system and, consequently, to the formation of an analogue of the single-pulse echo signal. The contribution of various signal formation mechanisms to the intensity of this signal is investigated.

在足够长的激励射频脉冲的后沿和前面的补充磁视频脉冲的共同影响下，获得了锂铁氧体中的单脉冲回波信号的模拟。回波信号是由于在幅度超过畴壁钉扎力的磁视频脉冲的作用下畴壁发生位移而产生的。这导致在旋转坐标系中作用在畴壁核上的有效场方向的突然变化，从而导致形成单脉冲回波信号的模拟。研究了各种信号形成机制对该信号强度的贡献。
