广义自旋-S磁性二元合金的磁滞特性

Hysteresis Characteristics of Generalized Spin-S Magnetic Binary Alloys

Gülşen Karakoyun, Ümit Akıncı

摘要:

本文在有效场近似下研究了广义自旋-S二元合金的磁滞特性,其表达式为$A_c B_{1-c}$。该系统由A型(自旋-S)和B型(自旋-S)原子组成,它们随机分布在蜂窝晶格上。研究了两种磁性原子的整数和半整数自旋模型。通过对滞回线的详细研究,得到了给定哈密顿参数下的多重滞回特性。此外,磁滞回线面积,剩磁,矫顽场等磁滞特性的数量已被调查作为浓度的函数。

英文摘要:

In this study, hysteresis characteristics of the generalized spin-S binary alloy represented by the formula $A_c B_{1-c}$ have been investigated within the framework of effective field approximation. The binary system consists of type A (spin-S) and type B (spin-S) atoms which are randomly distributed on a honeycomb lattice. Both integer and half-integer spin models of two magnetic atom types are examined. By detailed investigation on hysteresis loops, multiple hysteresis behaviors are obtained for a given set of Hamiltonian parameters. Besides, the quantities of hysteresis characteristics as the hysteresis loop area, remanent magnetization, and coercive field have been investigated as functions of concentration.
