摘要：

The temperature dependences of the magnetization and the quadrupolar moment in the spin-3/2 Blume-Capel model on honeycomb lattices are examined in detail by the use of new formulations based on both thc exact Ising spin identities and the differential operator technique. A number of characteristic behaviors for their thermal variations are obtained, especially for negative values of the crystal-field constant.
