Magneto-Coulomb Oscillation in Ferromagnetic Single Electron Transistors

Abstract

The mechanism of the magneto-Coulomb oscillation in ferromagnetic single\nelectron transistors (SET's) is theoretically considered. Variations in the\nchemical potentials of the conduction electrons in the ferromagnetic island\nelectrode and the ferromagnetic lead electrodes in magnetic fields cause\nchanges in the free energy of the island electrode of the SET. Experimental\nresults of the magneto-Coulomb oscillation in a Ni/Co/Ni ferromagnetic SET are\npresented and discussed. Possible applications of this phenomenon are also\ndiscussed.\n
