Abstract:In this work we studied the behavior of multi-channel tunneling through a realistic Fe/MgO/Fe hetero-junction ab initio potential. For this purpose we obtained Fe/MgO/Fe(001) hetero-junction effective potentials using the full potential-linear augmented plane wave WIEN2k code together with the generalized gradient approximation for the exchange-correlation potential. Multi-channel tunneling through the Fe/MgO/Fe hetero-junction barrier was studied within a few modes model. The transfer matrix technique was use… Show more
