SGER: Local Probing of Magnetization Switching using Vectorial Susceptibility Experiments

现代磁性器件的功能需要知道它们的开关特性，即临界曲线。建议SGER研究代表了一种新的方法来本地测量耦合纳米磁系统的开关临界曲线。这是一个非常具有挑战性的项目，因为一个新的想法耦合磁系统的临界曲线测量将进行测试，而宏观测量设备将与纳米磁性物体接口。 从该项目中获得的发现将有助于对纳米级物理现象，特别是纳米磁性的基本理解，为介观磁性结构的动态特性提供见解。社会的直接利益来自于拟议活动对磁记录技术的巨大影响。此外，该项目的成功可能会对路易斯安那州的纳米技术教育产生广泛的影响，使本科生，特别是少数民族，了解最新的研究进展。

The functioning of modern magnetic devices requires knowing their switching characteristics, i.e. critical curve. The proposed SGER research represents a new approach to locally measure the switching critical curve of coupled nanomagnetic systems. This is a very challenging project because a novel idea for critical curve measurement of coupled magnetic systems will be tested while macroscopic measurement devices will be interfaced with nanosized magnetic objects. The findings gained from this project will contribute to the basic understanding of the nanoscale physical phenomena, specifically nanomagnetism, providing insights into the dynamic properties of mesoscopic magnetic structures. The immediate benefit for the society comes from the big impact of the proposed activity on magnetic recording technology. Also, the success of this project could have broad impacts on nanotechnology education in the Louisiana by exposing undergraduates students, especially minorities, to the latest research developments.
