2020年10月2日 · The extracted SHA for Pt, $+20%$, is opposite to the one of Co/Ni, giving rise to an effective AHE inversion for thin Co/Ni multilayers (with the number of repetition layers $N<17$). The spin-Hall angle in Pt is found to be larger than the one previously measured by complementary spin-pumping inverse spin-Hall effect experiments in a geometry ...
Large intrinsic anomalous Hall effect in half-metallic ferromagnet Co
2018年9月11日 · Here, we report the quite large AHE in the half-metallic ferromagnet Co 3 Sn 2 S 2 single crystal. By systematically mapping out the electronic structure of Co 3 Sn 2 S 2 both theoretically...
Magnetoresistance and Anomalous Hall Effect with Pt Spacer
For the Co/Pt multilayers, other magnetotransport properties—magnetoresistance (MR) and anomalous Hall effect (AHE)—remain unclear in spin-valve structure. The MR has been extensively studied in multilayer systems because of their …
Large enhancement of the anomalous Hall effect in Co/Pt …
2010年11月30日 · We report a large enhanced anomalous Hall effect (AHE) in the Co/Pt multilayers sandwiched by two MgO layers. The Hall resistivity (ρ x y) was over an order of magnitude larger than that in pure Co/Pt multilayers. By optimizing the thickness of MgO layers, a high field sensitivity value of 2445 V/A T for Hall sensors was achieved.
Anomalous Hall Effect and Magneto-Optic Kerr Effect in Pt/Co/Pt …
2022年5月12日 · In this work, the mechanisms of AHE and magneto-optic Kerr effect in Pt/Co/Pt heterostructure have been studied. Our experimental results and data scaling relationships show that both SJ and SS contribute to the AHE in the Pt/Co/Pt heterostructured films and SS plays a dominant role in the AHE.
Giant room temperature anomalous Hall effect and tunable …
2020年7月10日 · In this work, we demonstrate the band topology modification via a weak magnetic field in a ferromagnetic Weyl semimetal candidate, Co 2 MnAl, at room temperature. We observe a tunable, giant...
Observation of two-channel anomalous Hall effect in …
2023年9月29日 · The two-channel AHE model is used to explain the origin of the sharp spikes associated with anomalous Hall effect. It indicates that the phase separation is the reason for the sharp spikes. In addition, the mixed valence state, ferrimagnetic order, and the electronic configuration in NCO films are further analyzed.
The anomalous Hall effect (AHE) has been recognized as a useful tool for measuring the magnetic hysteresis M(H) loops of perpendicular magnetic recording media (PMRM), and has shown particular utility for characterizing double-layered PMRM since the loops for both the recording layer (RL) and soft under layer (SUL) may be measured
直方图均衡化(HE, AHE, CLAHE) - CSDN博客
2021年4月22日 · 限制对比度自适应直方图均衡化(Contrast Limited Adaptive Histogram Equalization,CLAHE)是对AHE的改进。 CLAHE 在 AHE 的基础上引入了对比度限制机制,以避免在图像中出现过度增强的噪点。
二、自适应直方图均衡化(AHE) - CSDN博客
2024年12月6日 · 自适应直方图均衡化 (AHE)用来提升图像的对比度的一种计算机图像处理技术。 和普通的直方图均衡算法不同,AHE算法通过计算图像的局部直方图,然后重新分布亮度来改变图像对比度。 因此,该算法更适合于改进图像的局部对比度以及获得更多的图像细节。 缺点是有一个很大的缺陷,就是有时候会过度放大图像中相同区域的噪声。 限制对比度的直方图均衡化 (CLAHE)的处理方式是先为直方图设置一个阈值,该阈值为限制对比度值,超过该阈值的值会 …
