抄録

We theoretically analyze a magnetic wall confined in a nano-contact spin valve paying special attention to the penetration of the magnetic wall into thin ferromagnetic electrodes. We show that, compared with the Bloch wall, the penetration of the Neél wall is suppressed by increases of the demagnetization energy. We find the optimal conditions of the radius and height of the nano-contact to maximize the power of the current-induced oscillation of the magnetic wall. We also find that the thermal stability of the Bloch wall increases when the nano-contact's radius increases or height decreases.
