Abstract
It is shown that frustrations caused by additional spins result in a g reater variety of phases with commensurate and incommensurate periods as well as in the appearance of nonperiodic phases. It is established that a single-e modulated phase is unstable against zero-point motions . As a result, a disordered state with zero magnetization at a site ca n exist in a wide range of values of the frustration parameters.
