Unveiling temperature dependence mechanisms of perpendicular magnetic anisotropy at Fe/MgO interfaces
Fatima Ibrahim, Ali Hallal, Alan Kalitsov +3
The perpendicular magnetic anisotropy (PMA) at magnetic transition metal/oxide interfaces is a key element in building out-of-plane magnetized magnetic tunnel junctions for spin-tr…
Giant perpendicular magnetic anisotropy enhancement in MgO-based magnetic tunnel junction by using Co/Fe composite layer
Libor Vojáček, Fatima Ibrahim, Ali Hallal +2
Magnetic tunnel junctions with perpendicular anisotropy form the basis of the spin-transfer torque magnetic random-access memory (STT-MRAM), which is non-volatile, fast, dense, and…
Low-energy spin precession in the molecular field of a magnetic thin film
Christopher Vautrin, Daniel Lacour, Coriolan Tiusan +5
Electronic spin precession and filtering are measured in the molecular field of magnetic thin films. The conducted lab-on-chip experiments allow injection of electrons with energie…
Temperature dependence of transport mechanisms in organic multiferroic tunnel junctions
Can Xiao, Huawei Sun, Luming Cheng +14
Organic multiferroic tunnel junctions (OMFTJs) with multi-resistance states have been proposed and drawn intensive interests due to their potential applications, for examples of me…
Enhancement of ferroelectric performance in PVDF:Fe3O4 nanocomposite based organic multiferroic tunnel junctions
Xue Gao, Shiheng Liang, Anthony Ferri +16
We report on the fabrication of organic multiferroic tunnel junction (OMFTJ) based on an organic barrier of Poly(vinylidene fluoride) (PVDF):Fe3O4 nanocomposite. By adding Fe3O4 na…
Nitrogen magneto-ionics
Julius de Rojas, Alberto Quintana, Aitor Lopeandía +15
So far, magneto-ionics, understood as voltage-driven ion transport in magnetic materials, has largely relied on controlled migration of oxygen ion/vacancy and, to a lesser extent,…
