Abstract

This manuscript is devoted to studying the effect of the external magnetic field on the hydrogen molecule (

D_{2}^{+}

) ion in a 3-dimensional Gaussian potential quantum dot. One donor impurity is assumed to be on-center, and the other can move on the positive x-axis, which is assumed to be off-center. Using the Ritz variational method, the system’s ground state energy and binding energy are obtained as a function of quantum dot size, donor impurity distance, and magnetic field strength. The magnetic moment and magnetic susceptibility of the

D_{2}^{+}

ion impurity is also calculated.

外磁场对高斯GaAs量子点中D2+离子基态性质的影响

本文研究了外磁场对三维高斯势量子点中氢分子（D2+）离子的影响。假设一个给体杂质在中心上，另一个可以在正x轴上移动，假设是偏离中心。利用Ritz变分方法，得到了系统的基态能量和结合能作为量子点尺寸、供体杂质距离和磁场强度的函数。计算了D2+离子杂质的磁矩和磁化率。

期刊介绍： The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public. Main Categories: Full-length articles: Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged. In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications. The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications. The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism. Review articles: Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
