Micromagnetic studies of the magnetization change in magnetostrictive nanomagnets subjected to stress are performed for nanomagnets of different sizes. The interplay between demagnetization, exchange and stress anisotropy energies is used to explain the rich physics of size-dependent magnetization dynamics induced by modulating stress anisotropy in planar nanomagnets. These studies have important implications for strain mediated ultralow energy magnetization control in nanomagnets and its application in energy-efficient nanomagnetic computing devices.
针对不同尺寸的磁致伸缩纳米磁铁进行了磁各向异性应力下磁化变化的微磁研究。通过调节平面纳米磁铁的应力各向异性来诱导尺寸相关的磁化动力学，利用退磁场能、交换能和应力各向异性能之间的相互作用来解释其丰富的物理性质。这些研究对于在纳米磁铁中通过应变介导的超低能量磁化控制及其在节能纳米磁计算设备中的应用具有重要意义。
