Sustainability analysis of perpendicular anisotropy magnetic memory and platinum substitution

Perpendicular anisotropy Magnetic Random Access Memory (MRAM) can contribute reduced power consumption in electronic circuits. These spintronic devices also rely on materials like Co, Pt and Ru, having associated supply risk or environmental impact. A sustainability analysis of these devices shows, that the impact of the wafer substrate is much larger than that of the […]

Single-shot all-optical switching of magnetisation in Tb/Co multilayer-based MTJ

Atomistic spin simulations have been carried out to study the probability of all-optical switching of [Tb/Co] multilayered thin films. Playing with the composition of the sample, the material parameters and the fluence of the laser pulse we have shown the possibility to get single-shot all-optical switching. Since the first experimental observation of all-optical switching phenomena, […]

Giant Perpendicular Magnetic Anisotropy Enhancement in MgO-Based Magnetic Tunnel Junction by Using Co/Fe Composite Layer

Magnetic tunnel junctions with perpendicular anisotropy form the basis of the spin-transfer torque magnetic random-access memory (STT-MRAM), which is nonvolatile, fast, dense, and has quasi-infinite write endurance and low power consumption. Here, an alternative design of tunnel junctions comprising FeCoFe|MgO storage layers with greatly enhanced perpendicular magnetic anisotropy (PMA) is proposed, leveraging the interfacial PMA […]
