Highly interface-dependent spin transport in an Fe–Mn(DBTAA)–Fe single molecule spintronic device

Abstract

Understanding the spinterface between magnetic electrode and molecule, and realizing controllable spin filtering effect are crucial for the development of high-performance molecular devices, but still face a big challenge. Here,...

High-performance molecular spin filters based on a square-planar four-coordinate Fe complex and covalent pyrazine anchoring groups

“…One option is to use a nonmagnetic molecular bridge with magnetism introduced to the system through two magnetic electrodes. 11,19,21,22 For example, zigzag-edged graphene nanoribbons (zGNRs) are possible magnetic electrodes. Spin filtering is achievable in singlemolecule spintronic devices constructed with zGNR electrodes due to the parity matching principle of the wave functions of tunnelling electrons in all parts of the device (i.e., the left and right zGNR electrodes and the central molecule).…”

External fields effectively switch the spin channels of transition metal-doped β-phase tellurene from first principles

“…Magnetic memory technology has increased the need for reliable spin channel switching of physical stimuli. [1][2][3][4][5] In particular, the development of scalable non-volatile magnetic random-access memory (MRAM) has greatly benefited from the discovery of tunnel magnetoresistance (TMR) in spin channel-switching dependent magnetic tunnelling junctions (MTJs). [6][7][8][9] Nonetheless, because of the Joule effect, the electrodes' various parallel magnetic configurations increase the energy dissipation.…”

Gate-Tunable Spin Seebeck Effect and Pure Spin Current Generation in Molecular Junctions Based on Bipolar Magnetic Molecules

“…On the other hand, aimed at improving integration density and enhancing functionality, the emergent molecular spintronics, which exploits one or a few magnetic molecules as the channel region in spintronics devices, has attracted extensive research interest in recent years. − In general, charge currents are hard to avoid when spin currents flow through molecular spintronic devices. The generation of pure spin currents at a single-molecule level has been rarely reported so far, , and a general method is still lacking.…”
