Kp. Wellock et al., THE ROLE OF INTERFACE IMPURITIES IN CO CU GIANT MAGNETORESISTANCE MULTILAYERS/, Journal of magnetism and magnetic materials, 144, 1995, pp. 585-586
We have deposited impurities (An, Ge and Cu) at the interfaces of Co/C
u multilayers grown by MBE. It was found that small fractions of a mon
olayer of impurities dramatically affect the GMR.
