Abstract

In response to the growing need for a more accurate micromagnetic model to understand switching phenomenon in nanoscale magnets, we developed the capability to simulate two-dimensional polycrystalline grains using the Object Oriented Micromagnetic Framework (OOMMF). This addition allows users full flexibility in determining the magnetocrystalline anisotropy and axe in each grain as well as the inter- and intragranular exchange coupling strength.

面向对象微磁框架中二维多晶颗粒的实现。

为了满足对更精确的微磁模型来理解纳米级磁铁中的开关现象的日益增长的需求，我们开发了使用面向对象微磁框架(OOMMF)模拟二维多晶颗粒的能力。这种添加允许用户充分灵活地确定磁晶各向异性和斧头在每个晶粒以及间和粒内交换耦合强度。

期刊介绍： The Journal of Research of the National Institute of Standards and Technology is the flagship publication of the National Institute of Standards and Technology. It has been published under various titles and forms since 1904, with its roots as Scientific Papers issued as the Bulletin of the Bureau of Standards. In 1928, the Scientific Papers were combined with Technologic Papers, which reported results of investigations of material and methods of testing. This new publication was titled the Bureau of Standards Journal of Research. The Journal of Research of NIST reports NIST research and development in metrology and related fields of physical science, engineering, applied mathematics, statistics, biotechnology, information technology.
