Tunneling magnetoresistance in Si nanowires
New Journal of Physics, 2016 We investigate the tunneling magnetoresistance of small diameter semiconducting Si nanowires attached to ferromagnetic Fe electrodes, using first principles density functional theory combined with the non-equilibrium Green’s functions method for quantum ...

Strain-enhanced tunneling magnetoresistance in MgO magnetic tunnel junctions. [PDF]
Sci Rep, 2014 While the effects of lattice mismatch-induced strain, mechanical strain, as well as the intrinsic strain of thin films are sometimes detrimental, resulting in mechanical deformation and failure, strain can also be usefully harnessed for applications such as data storage, transistors, solar cells, and strain gauges, among other things.

One-dimensional tight-binding model for electron transport through ferromagnet/insulator/ferromagnet junction in B-field [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 We applied a one-dimensional tight-binding model to the study electron transport in a ferromagnetic metal-insulatorferromagnetic metal junction. We included a small external magnetic field perpendicular to the one-dimensional chain as a Zeeman Effect on

Length-induced large magnetoresistance in polyacene molecular spin valves
Results in Physics, 2021 With the help of first-principles method, an unusual length effect in polyacene molecular spin valves is revealed. It is found that beyond a critical length, the magnitude of tunneling magnetoresistance is significantly enhanced from 10% to 2500 ...

Tunneling Magnetoresistance in Noncollinear Antiferromagnetic Tunnel Junctions
Physical Review Letters, 2022 Antiferromagnetic (AFM) spintronics has emerged as a subfield of spintronics driven by the advantages of antiferromagnets producing no stray fields and exhibiting ultrafast magnetization dynamics. The efficient method to detect an AFM order parameter, known as the Néel vector, by electric means is critical to realize concepts of AFM spintronics.

Fractional magnetoresistance oscillations in spin-triplet superconducting rings
Communications Physics, 2023 Half-quantum vortices in spin-triplet superconductors are predicted to host Majorana zero modes and may provide a viable platform for topological quantum computation. Recent works also suggested that, in thin mesoscopic rings, the superconducting pairing

Anisotropic tunneling magnetoresistance and tunneling anisotropic magnetoresistance: Spin-orbit coupling in magnetic tunnel junctions [PDF]
Physical Review B, 2009 The effects of the spin-orbit interaction on the tunneling magnetoresistance of ferromagnet/semiconductor/normal metal tunnel junctions are investigated. Analytical expressions for the tunneling anisotropic magnetoresistance (TAMR) are derived within an approximation in which the dependence of the magnetoresistance on the magnetization orientation in ...
