Abstract

The conductance in ferromagnetic Ni nano-wire is quantized in units of 2e2/h in the absence of magnetic field, while the units switch to e2/h in the magnetic field. The fractional units of 0.7e2/h and 1.4e2/h with and without magnetic field appear under the application of high bias-voltage. The spin polarization and bias-voltage play an important role in the electric conduction.
