Strontium Ferromolybdate-Based Magnetic Tunnel Junctions

open access: yesApplied Sciences, 2022
Thin-film strontium ferromolybdate is a promising material for applications in room-temperature magnetic tunnel junction devices. These are spin-based, low-power-consuming alternatives to CMOS in non-volatile memories, comparators, analog-to-digital ...

A Brief Review of Ferroelectric Control of Magnetoresistance in Organic Spin Valves [PDF]

open access: yes, 2017
Magnetoelectric coupling has been a trending research topic in both organic and inorganic materials and hybrids. The concept of controlling magnetism using an electric field is particularly appealing in energy efficient applications.

Quantum simulation of ferromagnetic and anti-ferromagnetic tunneling anisotropic magnetoresistance in a single-molecule-magnet dimer tunnel-junction

open access: yesAIP Advances, 2019
In this work, we simulate the tunneling anisotropic magnetoresistance (TAMR) in a single-molecule-magnet (SMM) dimer tunnel-junction with metal and ferromagnetic (FM) electrodes.

Resonant Inversion of Tunneling Magnetoresistance

open access: yesPhysical Review Letters, 2003
Resonant tunneling via localized states in the barrier can invert magnetoresistance in magnetic tunnel junctions. Experiments performed on electrodeposited Ni/NiO/Co nanojunctions of area smaller than 0.01 microm(2) show that both positive and negative values of magnetoresistance are possible. Calculations based on Landauer-Büttiker theory explain this

Resistive switching and voltage induced modulation of tunneling magnetoresistance in nanosized perpendicular organic spin valves

open access: yesAIP Advances, 2016
Nanoscale multifunctional perpendicular organic spin valves have been fabricated. The devices based on an La0.7Sr0.3MnO3/Alq3/Co trilayer show resistive switching of up to 4-5 orders of magnitude and magnetoresistance as high as -70% the latter even ...

Magnetotransport effects of ultrathin Ni80Fe20 films probed in-situ

open access: yes, 2009
We have investigated the magnetoresistance of Permalloy (Ni80Fe20) films with thicknesses ranging from a single monolayer to 12 nm, grown on Al2O3, MgO and SiO2 substrates.

Conducting ballistic magnetoresistance and tunneling magnetoresistance: Pinholes and tunnel barriers [PDF]

open access: yesApplied Physics Letters, 2000
This letter shows that conducting ballistic and tunneling magnetoresistances have identical physical treatments and, therefore, it is not possible to distinguish whether an experiment is measuring, in oxide barriers, electron conduction through pinholes or tunneling because both types of conduction are governed by the same physics.

Resonant tunneling magnetoresistance in epitaxial metal-semiconductor heterostructures

open access: yes, 2005
We report on resonant tunneling magnetoresistance via localized states through a ZnSe semiconducting barrier which can reverse the sign of the effective spin polarization of tunneling electrons.

From ballistic transport to tunneling in electromigrated ferromagnetic breakjunctions [PDF]

open access: yes, 2005
We fabricate ferromagnetic nanowires with constrictions whose cross section can be reduced gradually from 100 nm to the atomic scale and eventually to the tunneling regime by means of electromigration.
