Paper Abstract

Analytical expression for a single-pulse nuclear echo signal in magnetically ordered materials has been obtained taking into account inhomogeneous broadening of spectroscopic transition and inhomogeneous distribution of enhancement factor with average value of 1. The summation of oscillations of nuclear magnetic moments with equal amplitudes and phases has been shown to take place every time in this signal. The cause for the effective suppression of oscillation of nuclear magnetic moments at the beginning of the free precession of the signal has been determined by analytical methods. The character of the dependence of a single-pulse echo signal amplitude on the tension of the external variable magnetic field, pulse duration and the width of the enhancement factor distribution has been revealed. The obtained results have been compared with experimental data observed in ferromagnetic polycrystalline sample Co2MnSi.
