Under the approximation of the mean field, Curie temperature and magnetization profiles of layer quantum Ising model with a transverse field were studied. The Curie temperature equation of the model was derived.The dependence of Curie temperature on the Fibonacci number n and the external field is given.It is found that the Curie temperature of quasiperiodic models is like to that of periodec models if the chain is long enough.With the same framework, the magnetization profiles of the system was also calculated.The method proposed here can be applied to other quasiperiodic model.
