摘要:

视向交叉是物理学中的一个经典课题。令人惊讶的是,它没有在微磁学中搜索,微磁学处理的是诸如畴壁(2D)和涡旋(1D)之类的物体。我们预测模拟这两个对象之间的二阶过渡,与壁长的朗道参数。这是基于微米尺寸的ux闭合点的实验证实的。

英文摘要:

Dimensionality cross-over is a classical topic in physics. Surprisingly it has not been searched in micromagnetism, which deals with objects such as domain walls (2D) and vortices (1D). We predict by simulation a second-order transition between these two objects, with the wall length as the Landau parameter. This was conrmed experimentally based on micron-sized ux-closure dots.
