GIANT MAGNETORESISTANCE OF (110)-ORIENTED NIFE/CU MULTILAYER GROWN ON MGO(110)

A multilayer consisting of 40 periods of NiFe (NiS1, Fe19 in wt%) and Cu, the thicknesses of which are 1 nm each, was deposited on an underlayer of 20 nm NiFe grown on a MgO(110) single-crystal substrate, A strongly anisotropic behavior in its magnetoresistive property is evident when the magnetic field is applied along the [110] and [001] directions. Its crystallographic relationship with the substrate is assigned as NiFe/Cu(110)//MgO(110) perpendicular to the plane of the film, and NiFe/Cu[1 $($) over bar$$ 101]//MgO[1 $($) over bar$$ 10], NiFe/Cu[001]//MgO[001] in the plane of the film.
