External Field Free Spin Hall Effect Device for Perpendicular Magnetization Reversal Using a Composite Structure with Biasing Layer

Angeline Klemm Smith、Mahdi Jamali、Zhengyang Zhao 等 4 位作者2016-02-08arXiv (Cornell University)

In this paper, a new material structure is proposed that utilizes the spin Hall effect to switch perpendicularly magnetized materials in the absence of any externally applied field. The structure consists of a multilayered material stack including a magnetic layer with perpendicular magnetic anisotropy that serves as…

External-Field-Free Spin Hall Switching of Perpendicular Magnetic Nanopillar with a Dipole-Coupled Composite Structure

Zhengyang Zhao、Angeline Klemm Smith、Mahdi Jamali 等 4 位作者2016-02-08arXiv (Cornell University)

Spin Hall effect (SHE) induced reversal of perpendicular magnetization has attracted significant interest, due to its potential to lead to low power memory and logic devices. However, the switching requires an assisted in-plane magnetic field, which hampers its practical applications. Here, we introduce a novel approa…

Magnetic Proximity Effects between Single-Layer Mn-Doped Titania Nanosheets and Fe Overlayers

Natsumi Saitou、Yuki Hirano、Masahiro Sawada 等 8 位作者2016-02-08Journal of the Physical Society of Japan

We have investigated the magnetic behaviors of molecularly thin Mn-doped titanium oxide nanosheets by X-ray magnetic circular dichroism. Mn atoms in single-layer nanosheets showed a weak ferromagnetic order at room temperature. Fe overlayers deposited on the nanosheets induced a magnetic proximity effect on Mn magneti…

Quantitative measurement of gas wettability of different substrates

Min Zhang、Guancheng Jiang、Shaojie Luo 等 7 位作者2016-02-08Energy Sources Part A Recovery Utilization and Environmental Effects

Both theory and experiments demonstrate that gas-wetness cannot always be overlooked and the gas-wet degree affects gas-well production greatly in gas condensate reservoirs. In the study, two quantitative methods have been introduced, the sessile drop and the captive bubble, and the corresponding wettability indexes,…

Current-Induced Domain-Wall Motion for Electron Flow in Ferromagnetic Pt/Co/Ni/Co/Pt Wires

Kwang‐Su Ryu、See‐Hun Yang、Luc Thomas 等 4 位作者2016-02-08IEEE Transactions on Magnetics

We report the current-induced domain-wall (CIDW) motion along the electron flow in the perpendicularly magnetized Co/Ni/Co structure sandwiched between the top and bottom Pt layers, observed by means of the Kerr microscope. As the lower Co thickness increases, the DW velocity for the electron flow is significantly inc…

Scale effects in the static response of a one-dimensional quasi-brittle damage lattice

Benjamin Hérisson、Vincent Picandet、Noël Challamel 等 4 位作者2016-02-08European Journal of Environmental and Civil engineering

In this paper, we investigate the failure of a discrete elastic-damage axial system using both a discrete and an equivalent continuum approach. The microstructured damage chain consists of a one-dimensional damage lattice with direct nearest–neighbour interactions, which is composed of a series of periodic elastic-dam…

Numerical Model of an Innovative Damping System Using Superelastic Shape Memory Alloy Rings

Nan Gao、Jong‐Su Jeon、Reginald DesRoches 等 4 位作者2016-02-08Geotechnical and Structural Engineering Congress 2016

Superelastic shape memory alloys (SMAs) are promising materials for seismic applications since they have the ability to not only dissipate energy but also restore their original shape after large deformations. This study aims to develop numerical models of shape memory alloy rings designed as a new seismic damping sys…
