Recently, it has been predicted that a spin-polarized electrical current perpendicular to plane directly flowing through magnetic element can induce magnetization switching spin-momentum transfer. In this Letter, the first observation of current-induced (CIMS) in exchange-biased spin valves (ESPVs) at room temperature is reported. The ESPVs show CIMS behavior under sweeping dc with very high critical density. It demonstrated thin ruthenium (Ru) layer inserted between free and top electrode...
In this research, I introduce a water surface elevation measurement method that combines point cloud processing techniques and stereo vision cameras. While current vision-based level focus on laboratory measurements or are based auxiliary devices such as rulers, investigated the feasibility of measuring images surface.

Current-perpendicular-to-plane (CPP) geometrical giant magnetoresistance (GMR) single spin-valve (SPV) structures with synthetic antiferromagnets (SyAFs) as free layers were fabricated. The sample sizes range from micron to submicron. We demonstrate that SyAFs dramatically enhances the CPP-GMR ratio 0.83% 3.56% at room temperature and also double resistance-area product in SPV films. A study of magnetic switching behavior by both experiment single-domain thermal activation modeling shows...
We study the current-perpendicular-to-plane giant magnetoresistance (CPP-GMR) and magnetic switching behavior of single spin-valve (SV) films with two different free layers---one is a ferromagnet (FM) layer, while other synthetic antiferromagnet (SyAF) consisting ${\mathrm{Co}}_{90}{\mathrm{Fe}}_{10}/{\mathrm{R}\mathrm{u}/\mathrm{C}\mathrm{o}}_{90}{\mathrm{Fe}}_{10}.$ When interlayer Cu thickness 2.5 nm, SyAF as layer greatly enhances CPP-GMR SVs from 0.8% to 3.6%. The GMR enhancement effect...
In this letter, we report on measurements of current-induced magnetization switching (CIMS) in current-perpendicular-to-plane exchange-biased spin-valves (ESPVs). The structures the ESPVs are all “antisymmetric,” but with different thickness a ruthenium (Ru) layer. It is confirmed that “antisymmetric” largely enhance spin transfer effect and therefore reduce critical current densities for CIMS. Ru layer also systematically studied. With decrease layer’s thickness, can be further reduced....

ABSTRACT The Ordos Basin is among China's largest petroliferous basins, with its southwestern part being a key exploration area. Prior studies indicated that the basin's internal structure was relatively simple, featuring minor developmental faults and primarily stratigraphic–lithologic reservoirs. However, recent research has identified numerous strike‐slip in basin, their relationship to oil gas accumulations remains unclear. This study, using integrated interpretations of field outcrops,...
