Topic Classical microelectronics is reaching its limits of downward scalability, reaching technological or scientific bottlenecks. Magnetic random access memories, based on magnetic tunnel junctions storing and reading bits of information, are emerging key ICT components. They are of immediate relevance for low-power and high-speed processor and mass-storage cache memory. Similar to other technologies, ways are […]
Read moreImpact of heating on the stability phase diagrams of perpendicular MTJs (February 19th, 2019)
Measured switching diagrams of perpendicular magnetic tunnel junctions exhibit unexpected behavior at high voltages associated with significant heating of the storage layer. The boundaries deviate from the critical lines corresponding to the coercive field, which contrasts with the theoretically predicted behavior of a standard macrospin-based model. In this paper, we are proposing a modified model […]

Read moreEfficient microwave amplification by heat modulation at GHz frequency in spintronics oscillators (November 13th, 2018)
Due to the nanometer size of magnetic tunnel junctions and high interfacial resistance of ultrathin MgO tunnel barriers, temperature modulation at GHz frequency can be achieved in these devices and efficiently use to amplify microwaves in spintronics oscillators. Spintronics oscillators use two major phenomena discovered in spin-electronics: the tunnel magnetoresistance of magnetic tunnel junctions (MTJ) […]
