摘要：
The critical behaviors of a mixed spin-(1/2)and spin-sIsing system with a transverse crystal field are studiedby use of the effective-field theory with correlations.The effect of the transverse crystal field on transition temperaturesis investigated numerically for the honeycomb(z=3)and square(z=4)lattices.The results show that there is notricritical point for the system.
