摘要：

Using an effective field theory with correlation we study a diluted mixed spin ferromagnetic system consisting of spin -1/2 and spin -1 with a crystal field interaction D. The influence of D on magnetic properties of the honeycomb lattice is discussed and a variety of interesting phase diagrams (in T/J, p) and (T/J, D/J) planes are given.
