- Abstract
We study spin-dependent tunneling through ferromagnetic quantum point contact. It was found that both the current and the conductance show increasing oscillatory fluctuations with the variation of Fermi energy and contact area at different temperatures. These oscillations are due to polarization inversion at the incoming of each new sub-band and increasing transmission probability through the higher sub-bands. The results are found to be in good concordance with those in the literature.
