PERPENDICULAR GIANT MAGNETORESISTANCE OF CO CU MULTILAYERS ON V-GROOVED SUBSTRATES - DEPENDENCE ON DEPOSITION METHOD/

The perpendicular giant magnetoresistance of Co/Cu multilayers grown a t an angle onto V-grooved InP substrates is studied using two differen t deposition techniques. Samples are grown both at ultra-high vacuum i n a molecular beam epitaxy system and in a classical high vacuum elect ron beam evaporation system, Using the two spin-channel model for elec tron transport, the spin-asymmetry parameters were determined. The abs olute value and temperature behavior of the spin-asymmetry parameters of the Co bulk scattering and the interface scattering are comparable for both series. We find that the interface scattering of the e-beam e vaporated multilayers is relatively less spin-dependent.
