摘要：
It is shown that frustrations caused by additional spins result in a greater 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 can exist in a wide range of values of the frustration parameters.
