evolution of magnetization textures in mn1.4ptsn under magnetic field
首发时间:2024-04-03
abstract:in this study, we used lorentz transmission electron microscopy (ltem) and the transport of intensity equation (tie) method to investigate the spin structures in the mn1.4ptsn magnet, which exhibits d2d symmetry. our goal was to observe how these spin structures evolve under the influence of an external magnetic field. in particular, the application of a perpendicular field was able to modulate the stripe domain widths and induce the formation of anti-skyrmions. while an in-plane magnetic field can control the state of these anti-skyrmions, the coexistence of different skyrmions suggests that the hysteresis properties of the magnet may affect the effectiveness of the field control.

外加磁场下mn1.4ptsn中磁结构的演变
摘要:在本文的研究中,我们使用洛伦兹透射电子显微镜(ltem)和强度传输方程(tie)的方法来研究具有d2d对称的 mn1.4ptsn 磁体中的自旋结构。我们的目标是观察这些自旋结构在外部磁场影响下的演变过程。特别是,垂直磁场的应用能够调节条纹畴的宽度,并诱导反斯格明子的形成。虽然面内磁场可以控制这些反斯格明子的状态,但不同斯格明子的共存表明,磁体的磁滞特性可能会影响磁场控制的有效性。
