Relaxation of geometrical frustration in three typical ways indicated by density of states

The relaxation of geometrical frustration under different factors is investigated by comparing the density of states and magnetic behavior obtained in Wang–Landau simulation. Starting from the same triangular antiferromagnetic system with high frustration, three typical ways, in which the non-trivial high degeneracy of ground states is lifted by different relaxative factors, are revealed. Correspondingly, the typical magnetic behavior with M0/3 (where M0 is the saturated magnetization) plateau in frustrated triangular system, shows distinct variations in these three cases.
