17 Jan 2007 | | Subject: | Mesoscopic Systems and Quantum Hall Effect; Materials Science | | Abstract: | We present results of numerical calculations of domain-wall resistance in the ferromagnetic semiconductor (Ga,Mn)As. We employ Landauer-Buttiker formalism and the tight binding method. Taking into account the full valence band structure we predict the magnitude of the domain-wall resistance without disorder and compare it to experimental values. Next we add disorder to the model and study numerically both small and large disorder regime. | | Source: | arXiv, cond-mat/0701398 | | Services: | Forum | Review | PDF | Favorites | |
