Ab Initio Investigation of a CoFeB/MgO/CoFeB Interface
Published online by Cambridge University Press: 01 February 2011
Abstract
We have carried out density functional calculations on a CoFeB/MgO/CoFeB interface with amorphous electrodes. The interface was shown to be stable with 4 mono-layers (ML) and to contain spin-polarized metal-oxigen bonds at the interface. The interfacial energy was estimated, to be used as a comparative measure of stability. In addition, the exchange-coupling indicated a favouring of the anti-paralell magnetization configuration with respect to the paralell for 4 ML.
