Determining how far a spin current propagates in a given material is a key fundamental endeavor in spintronics. In a typical ferromagnetic metal, a coherent spin current polarized transverse to the magnetization decays within just ~1 nm due to rapid spin dephasing.

Emerging spintronics nanodevices-based hybrid logic-in-memory architecture has recently been investigated to overcome these issues. Among them, spin-transfer-torque-based magnetic tunnel junction (STT-MTJ) nanopillar is one of the most promising spintronics nanodevices thanks to its We find an increase of the SMR ratio with a W capping layer thinner than 1.0 nm, which is attributed to the enhancement of the spin accumulation at the Pt/YIG interfacs.

This rapidly developing field of organic spintronics gained significant attention and was recently named ‘spinterface’ . It is the authors' opinion that these unusual (interface) properties place, for the first time, organic spintronics in a position that is truly competitive with that of inorganic spintronics [10,41].

Apr 16, 2020 Sub-100 nm ferromagnetic/antiferromagnetic nanodisks present enhanced magnetic properties with respect to their thin film counterparts.

The major problem is the realization and fabrication of spintronics based devices. Spintronics is a promising technology which aims to solve the major problems existing in today’s conventional electronic devices. Realistically, this technology has the ability to combine the main functions of the modern semiconductor microelectronics and magnetic storage devices in single chip.

The vital role played by porphyrins in cells and their use in therapeutic processes are well known. More recently, the technological applications of porphyrins have attracted the attention of researchers. Porphyrins have the property of half-metallic material, i.e., molecules that can host transition metals making feasible the production of spin-polarized electronic states at different channels.
