Abstract:In magnetic tunnel junctions (MTJ) for memory or sensor applications, insertion of Ta nanolayers at the interface of or within magnetic layers such as CoFe or NiFe is often employed to enhance the tunneling magnetoresistance (TMR), although it also locally reduces the magnetization and modifies the magnetic properties. To properly model the magnetic behavior of such structures, it is important to be able to accurately account for these modifications. In this paper we investigate, experimentally and by means of… Show more
