研究了垂直磁各向异性铁磁纳米线的畴壁钉扎和脱钉机制。微磁模拟结果表明，缺口处的退钉磁场仅由缺口间的差距决定，与线宽和缺口尺寸无关。双切口钢丝表现出两重贴花纸畴图案，其中一半图案与单切口钢丝相同。因此，双切口线显示出与具有半宽度的单切口线相同的脱钉场。（© 2008 WILEY-VCH Verlag GmbH & Co. KGaA，魏因海姆）
Domain-wall pinning and depinning mechanisms of ferromagnetc nanowires with perpendicular magnetic anisotropy were investigated. Micromagnetic simulation results revealed that the depinning field from notches were determined solely by the gap distance between the notches, irrespective to the wire width and the notch size. The double-notch wires exhibited two-fold decalcomanie domain patterns and one half patterns were identical to those of single-notch wires. Therefore, the double-notch wires showed the same depinning field compared to single-notch wires with half width. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
