| 中文摘要 | The order-disorder transition in a bilayer J(1)-J(2) model (with interlayer coupling J(0)) is studied by a bond-operator mean-field method. The phase diagram is obtained. On the Neel phase side, the critical interlayer coupling J(0)(c) decreases linearly with increasing frustration J(2) for J(2) less than or equal to 0.2 J(1) and extends down to zero at about J(2) similar or equal to 0.38 J(1). On the collinear phase side, J(0)(c) also exhibits a linear decrease with decreasing J(2) for J(2) greater than or equal to 1.0 J(1) and extends down to zero at about J(2) similar or equal to 0.60 J(1). The sublattice magnetizations of both the Neel phase and the collinear phase are calculated. Near the phase boundary, we have M proportional to (J(0)(c) - J(0))(1/2). The low-temperature quantum critical properties obtained are in agreement with those of the O(3) nonlinear sigma-model. |
