It is generally known that tunnel magnetoresistance (TMR) and resistance area (RA) are significantly affected by the ferromagnet/barrier interfaces. Here, we study the effect of CoFe insertion in Co₂FeAl/inserted CoFe (0 or 1 nm)/MgAl₂O₄/CoFe(001) MTJs on their crystal structure and spin-dependent transport properties.
