I-V asymmetry and magnetoresistance in nickel nanoconstrictions
We present a joint experimental and theoretical study on the transport properties of nickel nanoconstrictions. The samples show highly non-linear and asymmetric I-V characteristics when the conductance is smaller than G(0) = 2e(2)/h, and huge magneto resistance ratios exceeding 99.9%. We model a sin...
