Research Initiation: Domain Wall Structures and Dynamics ofMagnetic Bubbles in (110)-Oriented Garnet Films

为了更好地了解（110）取向石榴石薄膜中磁性气泡的静态和动态畴壁结构，采用了实验方法。将检查给定区域壁面结构稳定的速度范围，壁面结构发生变化的速度以及可以动态生成的壁面状态类型。采用旋转梯度法和二维梯度传播实验进行研究。旋转梯度法允许气泡的稳态传播，并产生在其他实验方法中无法获得的壁面结构信息。二维梯度传播技术将允许气泡在任意方向上传播。

Experimental methods are performed to better understand the static and dynamic domain wall structure of magnetic bubbles in (110)-oriented garnet films. The velocity range over which a given domain wall structure is stable, the velocities at which wall structural changes occur, and the types of wall states that can be dynamically generated will be examined. The rotating gradient method and a two-dimensional gradient propagation experiment will be used to perform the study. The rotating gradient method allows the steady-state propagation of a bubble and yields information on wall structure that is not available in other experimental methods. The two-dimensional gradient propagation technique will allow the propagation of the bubble in an arbitrary direction.
