Amplitude dependence of single-pulse nuclear echo in Eu3Fe5O12 ferrimagnetic

Abstract

An analytical expression for the amplitude of a single-pulse nuclear echo signal in an Eu3Fe5O12 ferrimagnetic that takes into account nonresonant excitation conditions, inhomogeneous broadening of the spectroscopic transition, and inhomogeneous distribution of the enhancement factor was obtained. The amplitude of the single-pulse echo signal as a function of the radio-frequency detuning from the NMR frequency was theoretically established to have two peaks. The analytical description of the behavior of the single-pulse echo signal agreed well with experimental data observed in the Eu3Fe5O12 ferrimagnetic.
