摘要：
The low-temperature properties of the spin S=1/2 ladder with anisotropic ferromagnetic legs are studied using the continuum limit Bosonization approach. The weak-coupling ground-state phase diagram of the model is obtained for a wide range of coupling constants and several unconventional gapless "spin liquid" phases are shown to exist for ferromagnetic coupling. The behavior of the ladder system in the vicinity of the ferromagnetic instability point is discussed in detail.
