Abstract

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.
