We predict a giant field-like spin torque, T⊥, in spin-filter (SF) barrier tunnel junctions in sharp contrast to existing junctions based on nonmagnetic passive barriers. We demonstrate that T⊥ has linear bias behavior, is independent of the SF thickness, and has odd parity with respect to the SF’s exchange splitting. Thus, it can be selectively […]

We proposed the superior spin injection in amine-ended single-molecule magnetic junction (SMMJ) under stretching process, resulting from the strong hard-hard spinterfacial coupling between Co nanowire and amine linker. Furthermore, we predict anomalous magnetoresistance (MR) effect, including strain-induced sign reversal and bias-induced enhancement of MR value in amine-ended SMMJ with Co tip-like nanowire, which is in […]

With more and more the jobs you ran, the working files occupy the storage. User should periodically clean the unused files to keep our space free. This article provides some useful commands to find out the files you want to delete. Find files by pattern in a directory If you want to find out files […]

We propose a comprehensive theoretical investigation for the angular, external bias and mechanical strain dependence of the giant field-like spin torque (FLST) effect for amine-ended Co/BDA/Co single-molecule magnetic junctions in the non-collinear magnetic configuration, by employing our newly developed nonequilibrium Green’s function method within the framework of density functional theory.

We proposed a single-molecule magnetic junction (SMMJ), composed of a dissociated amine-ended benzene sandwiched between two Co tip-like nanowires. To better simulate the break junction technique for real SMMJs, the first-principles calculation associated with the hard-hard coupling between a amine-linker and Co tip-atom is carried out for SMMJs with mechanical strain and under an external […]

We propose analytic expressions for fieldlike, T⊥, and spin-transfer, T, spin torque components in the spin-filter-based magnetic tunnel junction (SFMTJ), by using the single-band tight-binding model with the nonequilibrium Keldysh formalism. In consideration of multireflection processes between noncollinear magnetization of the spin-filter (SF) barrier and the ferromagnetic (FM) electrode, the central spin-selective SF barrier plays […]

This article won’t teach you how to use and write Matlab. Here I just collect some useful links systematically which focus on specified topic. I hope this “bone” can help you to get basic concepts of Matlab quickly while how to fulfill the “meat” still needs you effect. The main references are WikiBook for Matlab […]
