Sažetak
We present experiments of the magnetization reversal by spin injection obtained on the pillar-shaped Co/Cu/Co trilayers. The pillars are fabricated by e- beam lithography and reactive ion etching. Their small section (200 x 600 nm^2) allowed the injection a current density of about 10^7 A/cm^2. Our data confirm similar previous results by the Cornell's group. In addition, we present a new type of experiment, which also evidences clearly the control of the magnetic configuration by the current intensity. The interpretation is based on the Slonczewski’s equations with a calculation of the current spin polarization based on the VF model of CPP-GMR. This type of calculation predicts right order of magnitude of the critical currents, but some discrepancy between calculation and experiments for the critical current asymmetry and their field dependence remains.
