Granular Thin(细粒状)研究综述
Granular Thin 细粒状 - Inspired by human’s granular thinking and the cognition law of “global precedence”, the human cognition process is from coarser granularity to finer granularity. [1] Our work shows that dilation during shear loading contributes to frictional strength via volume strain and that apparent friction scales inversely with the granular thinning ratio. [2] We offer a simple, high-resolution alternative by addressing the ubiquitous surface magnetization of magnetoelectric antiferromagnets in a granular thin-film sample on the nanoscale using single-spin magnetometry in combination with spin-sensitive transport experiments. [3]受人类颗粒思维和“全局优先”认知规律的启发,人类的认知过程是从粗粒度到细粒度的。 [1] 我们的工作表明,剪切载荷期间的膨胀通过体积应变有助于摩擦强度,并且表观摩擦与颗粒变薄率成反比。 [2] 我们通过使用单自旋磁力测量法结合自旋敏感传输实验来解决纳米级颗粒薄膜样品中磁电反铁磁体普遍存在的表面磁化问题,从而提供一种简单、高分辨率的替代方案。 [3]
granular thin film 粒状薄膜
In this paper, we have investigated structural and magnetic properties of CoFe–Cu granular thin films as a function of ferromagnetic layer pulse time (tCoFe). [1] The smooth P-h curves reflect a homogenous deformation mode, which is attributed to the activation of shear transformation zones (STZs) in the nanoscale granular thin films that could reasonably restrain the formation of shear bands. [2] We compare continuous and nanogranular thin films and emphasize the impact of the finite size on the remagnetization dynamics. [3]在本文中,我们研究了 CoFe-Cu 颗粒状薄膜的结构和磁性与铁磁层脉冲时间 (tCoFe) 的关系。 [1] 平滑的 P-h 曲线反映了均匀的变形模式,这归因于纳米级颗粒薄膜中剪切转变区 (STZ) 的激活,可以合理地抑制剪切带的形成。 [2] 我们比较了连续薄膜和纳米颗粒薄膜,并强调了有限尺寸对再磁化动力学的影响。 [3]
