摘要：

The quantum Heisenberg spin glass model with uniaxial anisotropy is investigated for the spin dimensionality S = 1 within the Trotter-Suzuki approach. The critical value of the anisotropy parameter D is found to be -2.725J, +/- 0.075J, lying between those of previous calculations by the static approximation and the thermofield-dynamical method, respectively.
