An Electromagnet-Based Magnetically-Activated Thermal Switch Without Moving Parts
C. Rodrigues, M. M. Dias, L. Martins +4
With the ever increasing power dissipation in electrical devices, new thermal management solutions are in high demand to maintain an optimal operating temperature and efficient per…
Influence of Thickness and Contact Area on the Performance of PDMS-Based Triboelectric Nanogenerators
A. Gomes, C. Rodrigues, A. M. Pereira +1
Triboelectric nanogenerators (TENGs) are an emerging mechanical energy harvesting technology that was recently demonstrated. Due to their flexibility, they can be fabricated in var…
Femtosecond control of electric currents at the interfaces of metallic ferromagnetic heterostructures
T. J. Huisman, R. V. Mikhaylovskiy, J. D. Costa +8
The idea to utilize not only the charge but also the spin of electrons in the operation of electronic devices has led to the development of spintronics, causing a revolution in how…
Quantum effects in atomically perfect specular spin valve structures
J. M. Teixeira, J. Ventura, Yu. G. Pogorelov +1
A simple tight-binding theoretical model is proposed for spin dependent, current-in-plane transport in highly coherent spin valve structures under specularity conditions. Using qua…
Dielectric breakdown in underoxidized magnetic tunnel junctions: Dependence on oxidation time and area
J. Ventura, R. Ferreira, J. B. Sousa +1
Magnetic tunnel junctions (MTJs) with partially oxidized 9 ÅAlO-barriers were recently shown to have the necessary characteristics to be used as magnetoresistive sensors in hig…
Nanoscopic processes of Current Induced Switching in thin tunnel junctions
J. Ventura, J. P. Araujo, J. B. Sousa +3
In magnetic nanostructures one usually uses a magnetic field to commute between two resistance (R) states. A less common but technologically more interesting alternative to achieve…
