Large Magnetoresistance in Co/Ni/Co Ferromagnetic Single Electron Transistors
R. S. Liu, H. Pettersson, L. Michalak +3
We report on magnetotransport investigations of nano-scaled ferromagnetic Co/Ni/Co single electron transistors. As a result of reduced size, the devices exhibit single electron tra…
