摘要

利用分子平均场近似（MMFA）研究了铁磁混合自旋简单三次体系。在伊辛模型的基础上对研究结果进行了检验。研究了晶体磁场和外加磁场对混合自旋为3/2和自旋为9/2的blme - capel - Ising简单立方晶格的铁磁性和磁滞特性的影响。通过感兴趣的晶体场值，可以诱导出补偿现象。另一方面，当KBT/|J| = 1,1.5和2.5 Ko时，在各向异性值DA/|J| = -6.0和DB/|J| = -2.0时，所提出的铁磁体中出现了新的迟滞行为形式。

Ferrimagnetism and hysteresis behavior of a mixed spin ferrimagnetic Blume-Capel Ising system

Ferrimagnetic mixed spin simple cubic system is investigated using the molecular mean-field approximation(MMFA). The results of the research work have been checked on the basis of Ising model. It has been studied the effects of crystal and external magnetic fields on ferrimagnetism and Hysteresis behaviors of a mixed spin-3/2 and spin-9/2 Blume-Capel Ising simple cubic lattice, respectively. Through interesting crystal fields values, one may induce compensation phenomenon. On the other hand, new forms of Hysteresis behaviors in the proposed ferrimagnet have been obtained at values of anisotropies D_A/|J| = -6.0 and D_B/|J| = -2.0, for K_BT/|J| = 1,1.5, and 2.5 K^o, respectively.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
