The electronic and magnetic structures of the CoFeB|Ta and CoFe|TaB heterostructures were investigated from first principles in an attempt to clarify the effect of the Ta layer on the energetic stability and magnetisation of the heterostructures, which are used in magnetic random access memory devices.
