A mixed spin-(3,7/2) Blume-Capel ferrimagnetic model has been investigated. The mixed ferrimagnetic model with the nearest neighbor interactions on square and simple cubic lattices, is examined in the molecular mean field method. Some interesting features of long-range order are obtained depending not only on the crystal fields values for both sublattices but on the lattices structures. Characteristic critical points, i.e., many ferrimagnetic compensation temperatures of the model have been predicted as well. New results for a cubic lattice have been given that they stimulate an experimental work in the molecular-based magnetic compounds.

方形和简单立方晶格的混合自旋 3 和自旋 7/2 Blume-Capel 系统的磁特性

已经研究了混合自旋-(3,7/2) Blume-Capel 亚铁磁模型。在方形和简单立方晶格上具有最近邻相互作用的混合亚铁磁模型在分子平均场方法中进行了检查。获得长程有序的一些有趣特征不仅取决于两个亚晶格的晶体场值，还取决于晶格结构。特征临界点，即模型的许多亚铁磁补偿温度也已被预测。已经给出了立方晶格的新结果，它们刺激了基于分子的磁性化合物的实验工作。
