| Abstract: | The spin-1 Ising system with bilinear and biquadratic interactions has been studied by the combination of the quantum statistical mechanics with the two-spin cluster approximation in face-center-cubic lattice. By use of the Qnsager theory, The behaviors of the spin-1 system such as the relaxation times, the sound attenuation were obtained near the second-order phase transition. |
| Keywords: | spin-1 Ising system the two-spin cluster approximation the Onsager theory |
