Abstract: The method of the double-time temperature Green function is used to study theoretically the magnetic properties of a mixed spin-3/2 and spin-5/2 Heisenberg ferrimagnetic system on a layered honeycomb lattice. Particularly, the effects of single-ion anisotropy and interlayer interaction on magnetization, critical and compensation temperature are investigated. Gives the temperature dependence of the total and sublattice magnetization for several values of single-ion anisotropy and interlayer interaction, as well as the critical and compensation temperature as functions of single-ion anisotropy and interlayer interaction. All these indicate that there are several magnetization curves and there will be a compensation behavior only when the single-ion anisotropy and interlayer interaction exceed a minimum (D1min/J and J1min/J). The compensation temperature decreases with increasing D1/J and J1/J and it will remain unchanged as a consequence.
