Shape anisotropy revisited in single-digit nanometer magnetic tunnel junctions

open access: yesNature Communications, 2018
The thermal stability impedes the application of nanoscale magnetic tunnel junctions in electronic and spintronics devices. Here the authors achieved current-induced magnetization switching in magnetic tunnel junctions smaller than 10 nm with sufficient ...

Numerical renormalization group study of the Loschmidt echo in Kondo systems

open access: yesScientific Reports, 2022
We study the dynamical properties of the one-channel and two-channel spin-1/2 Kondo models after quenching in Hamiltonian variables. Eigen spectrum of the initial and final Hamiltonians is calculated by using the numerical renormalization group method ...

Spin effects on transport and zero-bias anomaly in a hybrid Majorana wire-quantum dot system

open access: yesScientific Reports, 2023
We examine the impact of spin effects on the nonequilibrium transport properties of a nanowire hosting Majorana zero-energy modes at its ends, coupled to a quantum dot junction with ferromagnetic leads.

Spintronics in antiferromagnets [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011
Magnetic domains and the walls between are the subject of great interest because of the role they play in determining the electrical properties of ferromagnetic materials and as a means of manipulating electron spin in spintronic devices.

Large spin accumulation and crystallographic dependence of spin transport in single crystal gallium nitride nanowires

open access: yesNature Communications, 2017
Semiconductors are promising for high performance spintronics but the low functioning temperature hampers their applications. Here the authors achieve a strong room temperature modulation of spin-dependent resistance in GaN nanowires, which marks an ...

Spintronics: A contemporary review of emerging electronics devices

open access: yesEngineering Science and Technology, an International Journal, 2016
Spintronics is a new field of research exploiting the influence of electron spin on the electrical conduction (or current is spin dependent). The major problem is the realization and fabrication of spintronics based devices.

Organic Spintronics: A Theoretical Investigation of a Graphene-Porphyrin Based Nanodevice

open access: yes, 2020
Spintronics is one of the most exciting applications of graphene-based devices. In this work Density Functional Theory is used to study a nanojunction consisting of two semi-infinite graphene electrodes contacted with an iron-porphyrin (FeP) molecule ...

Local bifurcation with spin-transfer torque in superparamagnetic tunnel junctions

open access: yesNature Communications, 2022
There has been much interest in using the probabilistic switching of magnetic tunnel junctions in unconventional computing, but to do so requires a detailed understanding of this switching. Here, Funatsu et al rigorously determine the switching exponents

Boosting spintronics with superconductivity [PDF]

open access: yes, 2021
Spintronics aims to utilize the spin degree of freedom for energy-efficient, non-volatile memory and logic devices. In this research update, we review state-of-the-art developments and new directions in charge- and spin-based memory/logic with a focus on

Hybrid photon–phonon blockade

open access: yesScientific Reports, 2022
We describe a novel type of blockade in a hybrid mode generated by linear coupling of photonic and phononic modes. We refer to this effect as hybrid photon–phonon blockade and show how it can be generated and detected in a driven nonlinear optomechanical
