Results are presented for the first experiments in phase conjugation with degenerate four-wave mixing of cw laser radiation in a stratifying solution. It is shown that solutions with a low critical stratification point may serve as the basis of fundamentally new recording media with an effective nonlinearity parameter ^/^/>10-3cm2/W.
