摘要： A racetrack memory device facilitates the manipulation of a series of domain walls along the racetrack. The racetrack is designed so that the domain wall energy increases and decreases in a continuous fashion between adjacent pinning sites, so that a domain wall does not become stuck between them. The variation in the domain wall energy along the racetrack can be provided by continuous variations of the racetrack's width (while maintaining constant thickness) and/or cross-sectional area (in which the racetrack dimensions are varied in both directions perpendicular to the length of the racetrack). Alternatively, this variation in domain wall energy may be provided by varying the magnetic properties of the racetrack along the racetrack while otherwise keeping the shape and size of the racetrack unchanged. In addition, variations of the racetrack's composition and/or shape can be used.

摘要： A method for use with a magnetic racetrack device includes placing domain walls having a first structure and domain walls having a second, different structure along the racetrack at stable positions corresponding to different regions within the device. The domain walls having the first structure and the domain walls having the second structure occupy alternating positions along the racetrack. A current pulse is applied to the racetrack, so that each of the domain walls moves to an adjacent region. This results in a transformation of the domain walls having the first structure into domain walls having the second structure, and vice versa. The first structure may be a vortex structure and the second structure may be a transverse structure.
摘要翻译：一种与磁性跑道装置一起使用的方法包括将具有第一结构的畴壁和具有第二不同结构的畴壁沿着跑道安置在对应于装置内不同区域的稳定位置处。具有第一结构的畴壁和具有第二结构的畴壁占据沿着跑道的交替位置。电流脉冲施加到赛道，使得每个畴壁移动到相邻区域。这导致具有第一结构的畴壁的转变为具有第二结构的畴壁，反之亦然。第一结构可以是涡流结构，第二结构可以是横向结构。
