SPIN WAVES IN A FERROMAGNETIC METAL (Journal Article).

It is worth noting that a large spin Hall angle (0.098) of NiFe is obtained, which is comparable with Pt. This work provides a kind of FM/AFM exchange bias structure to detect the spin current by charge signals, and highlights that ISHE in ferromagnetic metals can be used in spintronic research and applications. Received 26 May 2015. Studies of ferromagnetic metals by electron spin polarized tunneling. When ferromagnetic materials are used in applications like an iron-core solenoid, the relative permeability gives you an idea of the kind of multiplication of the applied magnetic field that can be achieved by having the ferromagnetic core present.So for an ordinary iron core you might expect a magnification of. Spin current generated in a ferromagnetic metal (FM) can be divided into two types. While one is magnetization dependent and induced by the well-known anomalous Hall effect, the other is a magnetization-independent spin Hall effect which is similar to that in a paramagnetic heavy metal (HM).

Ferromagnetic Material - an overview | ScienceDirect Topics.

A variety of phenomena at the interface between ferromagnetic (FM) and non-magnetic (NM) thin-film multilayered systems control nanomagnetic and spintronic behavior, the most significant being spin-dependent transport across the FM/NM interfaces, which underpins both giant 1,2 1. M. N. History. Ferromagnetic resonance was experimentally discovered by V. K. Arkad'yev when he observed the absorption of UHF radiation by ferromagnetic materials in 1911. A qualitative explanation of FMR along with an explanation of the results from Arkad'yev was offered up by Ya. G. Dorfman in 1923 when he suggested that the optical transitions due to Zeeman splitting could provide a way to study.

Spin-polarized plasmon in ferromagnetic metals - ScienceDirect.

Jul 05, 2016 · Upon the injection of a pure spin current, a ferromagnet, similar to a nonmagnetic metal, also exhibits inverse spin Hall effect (ISHE). We show in Co/Cu/YIG, where the thin Cu layer allows transmission of spin current from YIG into Co but decouples the two ferromagnets, that the interaction between ISHE and ferromagnetic ordering in Co can be unambiguously investigated.. Jul 08, 2022 · The magnetism in ferromagnetic materials is caused by the alignment patterns of their constituent atoms, which act as elementary electromagnets. Some species of atoms possess a magnetic moment ; that is, such an atom itself is an elementary electromagnet produced by the motion of electrons about its nucleus and by the spin of those electrons.

Determining spin-torque efficiency in ferromagnetic metals.

Physics Advances in Condensed Matter Physics In the framework of scattering theory, we study the tunneling conductance in a system including two junctions, ferromagnetic metal/normal metal/ferromagnetic superconductor, where ferromagnetic superconductor is in spin-singlet -wave pairing state. The simplest method of generating a spin-polarised current in a metal is to pass the current through a ferromagnetic material. The most common applications of this effect involve giant magnetoresistance (GMR) devices. A typical GMR device consists of at least two layers of ferromagnetic materials separated by a spacer layer. For example, a spin-polarized electron in a ferromagnet would be in a superposition of spin-mixed states, and this superposition can evolve toward an unpolarized state. Thus, spin mixing provides an intrinsic mechanism of spin relaxation in a ferromagnet.

Ultrafast optically induced spin transfer in ferromagnetic.

The magnetoresistance of ferromagnetic metals due to spin fluctuation through s-d interaction is calculated for the whole temperature region and for the weak magnetic field. The ladder approximation (RPA) is used in the calculation of the spin Green's functions and it is shown that the magnetoresistance has a logarithmic dependence on the.

Ferrimagnetic Materials - Properties, Applications, Types and.

Specifically, we experimentally study basic spin-current physics in a ferrimagnet (CoGd) and an antiferromagnet (Cr). We choose CoGd because adjusting its chemical composition allows us to easily tune its magnetism from ferromagnet-like (uncompensated magnetization) to antiferromagnet-like (compensated magnetization).

Generation and Detection of Dresselhaus‐Like Spin Current in a Single.

Dec 01, 2021 · In conventional inorganic ferromagnetic materials, photo-magnetic coupling is attributed to the spin-orbit-photon interaction. In this study, organic ferromagnetic crystals with negligible orbital angular momentum were developed, where direct spin-photon interaction–induced photo-magnetic coupling was observed. Using the field angular-dependent, spin-torque ferromagnetic resonance technique, we quantify the IP and OOP SOT efficiencies of 0.018 ± 0.003 and 0.047 ± 0.002 in the pure Py, respectively.

Manipulation of pure spin current in ferromagnetic metals.

Oct 23, 2020 · This compound displays ferromagnetic behavior with a spin ordering temperature as high as 600 K. Benefiting from the semiconducting direct bandgap (~2.28 eV), a field-tunable green fluorescent. Spin current generated in a ferromagnetic metal (FM) can be divided into two types. While one is magnetization dependent and induced by the well-known anomalous Hall effect, the other is a magnetization-independent spin Hall effect which is similar to that in a paramagnetic heavy metal (HM). Here, we study the magnetization-independent spin Hall. 26 minutes ago · However, to build spintronic devices, the properties of the materials are crucial. In most materials, the spin-up and spin-down magnetic moments cancel each other, making them unsuitable for spintronic applications. In ferromagnetic materials, particles with the same spin state can accumulate in a majority-up and majority-down domains.
