Shape-dependent Depinning of a Domain Wall by a Magnetic Field and a Spin-Polarized Current (1006.4138v1)
Published 21 Jun 2010 in cond-mat.other
Abstract: The effect of sample shape on the depinning of the domain wall (DW) driven by an applied magnetic field or a spin-polarized current is studied theoretically. The shape effect resulting from the modulation of the sample width (geometric pinning) can essentially affect the DW depinning. We found a good agreement between the ratios of the critical values of the magnetic field and the spin-polarized current predicted by the theory and measured in the experiment.
