Tunnel Magnetoresistance in Self-Assemblies of Exchange Coupled Core/Shell Nanoparticles

Fernando Fabris, Enio Lima, Cynthia Quinteros +8

We report the precise control of tunneling magnetoresistance (TMR) in devices of self-assembled core/shell Fe${}_3$O${}_4$/Co${}_{1-x}$Zn${}_x$Fe${}_2$O${}_4$ nanoparticles ($0\le x\le 1$).…
