Abstract :
Films for magnetic tunnel junctions (MJT) were grown by molecular beam epitaxy (MBE) method using interconnected III-V and II-VI growth chambers without breaking ultrahigh vacuum. A very high tunnel magnetoresistance (TMR) effect in the fully epitaxial Ga1-xMnxAs/ZnSe/Ga1-xMnxAs MTJ is reported.
