Control of spin injection by direct current in lateral spin valves
Fèlix Casanova, Amos Sharoni, Mikhail Erekhinsky +1
The spin injection and accumulation in metallic lateral spin valves with transparent interfaces is studied using d.c. injection current. Unlike a.c.-based techniques, this allows i…
Multiple Avalanches Across the Metal-Insulator Transition of Vanadium Oxide Nano-scaled Junctions
Amos Sharoni, Juan Gabriel Ramírez, Ivan K. Schuller
The metal insulator transition of nano-scaled devices is drastically different from the smooth transport curves generally reported. The temperature driven transition occurs…
Manifestation of the Verwey Transition in the Tunneling Spectra of Magnetite Nanocrystals
Pankaj Poddar, Tcipi Fried, Gil Markovich +4
Tunneling transport measurements performed on single particles and on arrays of Fe3O4 (magnetite) nanocrystals provide strong evidence for the existence of the Verwey metal-insulat…
