Post-doctoral position: development of hybrid ferroelectric-spintronics memories and post-CMOS devices (September 08th, 2022)
Keywords: Microelectronics, spintronics, ferroelectrics, Fe-RAM, Fe-FET, Design, post-CMOS electronics Summary: Spintronics devices involve ferromagnetic elements with high switching energies. Contrastingly, the polarization of ferroelectrics can be easily switched by an electric field, at energies typically 1000 times lower. This makes ferroelectrics good candidates for ultralow-power neuromorphic AI architectures. We recently demonstrated in a Nature article […]

Read morePerpendicular-shape-anisotropy MRAM do not fear temperature (September 01st, 2022)
Perpendicular-shape-anisotropy magnetic random-access memory (PSA MRAM) has been proposed to maintain the thermal stability of solid-state magnetic bits down to a few nanometers in diameter. Here we confirm directly with high-spatial resolution and high-sensitivity electron holography that magnetization is weakly affected by temperature, in contrast with the conventional ultrathin MRAM cells. Magnetic random-access memory (MRAM) […]
Read moreUnveiling temperature dependence mechanisms of perpendicular magnetic anisotropy at Fe/MgO interfaces (August 30th, 2022)
A recent breakthrough in understanding the thermal effects on the magnetic properties of perpendicularly magnetized Fe/MgO interfaces is reported. It turns out that the macroscopic mechanisms play a decisive role in determining the thermal stability of magnetization in such structures. The perpendicular magnetic anisotropy (PMA) at magnetic transition metal/oxide interfaces(TM/Ox) is a key element in […]

Context. Spintronics has become a mature technology for applications, such as magnetic field sensing and solid-state memories. However, existing concepts are almost exclusively based on planar processes such as thin film deposition and patterning. Extending spintronics to 3D devices would provide new integrated functionalities such as three-dimensional magnetic field sensors, and also open prospects for […]
