NUCLEAR SPIN ECHO IN MAGNETICS WITH INHOMOGENEOUS HYPERFINE AND QUADRUPOLE INTERACTION

Additional spin-ocho signale from quadrupole nuclei with I=7/2 (Co59 nuclei in Co and Fe−Co thin films) were investigated. It has been shown, that the time dependence of the additional ocho signals, arising at the time moments 2nς reflect quadrupole interaction inhomogenety.
