Abstract

We present measurements of tunneling magnetoresistance (TMR) in single-wall carbon nanotubes attached to ferromagnetic contacts in the Coulomb blockade regime. Strong variations of the TMR with gate voltage over a range of four conductance resonances, including a peculiar double-dip signature, are observed. The data are compared to calculations in the “dressed second order” (DSO) framework. In ...
