Ferroelectric-type phase transition with a critical dynamic central peak, induced by Cu2+(Ta)-Vo centeras as a slowest relaxator or oscollator in KTO:Li, is considered as an eta'enhancement cause. A possibility of incommensurate phase induced by Cu2+-Vo centers and cluster-induced coopertive behavior is discussed too.
