Paulo Coelho

Research Engineer
Micro and Nanofabrication Facility

Paulo joined INL (January 2018) as a Research Engineer in the Spintronics group, department of Nanoelectronics Engineering, under the supervision of Ricardo Ferreira. He is currently working on the large-scale microfabrication and characterization of magnetic field sensors based on magnetic tunnel junction technology.

Paulo obtained is MSc in Physics Engineering from Instituto Superior Técnico in 2014 where worked at INESC-MN on the development of magnetic flux concentrators with a gap size below 1um coupled to nanometric spin valve sensors. In 2018, he obtained his PhD in Physics from the Université Grenoble-Alpes (France) where he studied and developed double barrier magnetic tunnel junctions with in-plane and out-of-plane anisotropy for magnetoresistive random access memories controlled by spin transfer torque (STT-MRAM) at SPINTEC labs (CEA Grenoble). His research was dedicated to the study of the interplay between in-plane and out-of-plane torques in double magnetic tunnel junctions with in-plane magnetization. Besides, he demonstrated the modulation of spin transfer torque in sub-300nm perpendicular double magnetic tunnel junctions for improved read and write operations in STT-MRAM. He holds a patent for the development of a seedless multilayer with enhanced perpendicular anisotropy to be used as a top reference in perpendicular magnetic tunnel junctions.
