Three-pulse spin echo signals from quadrupolar nuclei in magnetic materials.
The time evolutions of the three-pulse spin echo signals from quadrupolar nuclei (63)Cu and (53)Cr in ferromagnetic CuCr(2)S(4):Sb have been investigated at the temperature T=77K. The experimental results were well explained by the developed theory of the time evolutions of the three-pulse echoes. The main assumption of this theory is the assumption that the temporal fluctuations in the electron magnetization lead to the fluctuations in the hyperfine and quadrupole interaction Hamiltonians.
