Abstract |
The magnetoresistance (MR) and the saturation resistivity (ρs) are studied versus the Cu deposition pressure (PCu) at room temperature, in [Co98Zr2 (25Å)/Cu (tCu) /Co (25Å)] magnetic sandwiches prepared by RF diode sputtering. Results of low angle X-Ray Diffraction patterns have been proved the importante interfacial degradation observed in (CoZr/Cu) multilayers, compared to the usual (Co/Cu) structures. The highest value of transverse MR is obtained along the easy axis, and the MR curve saturates in a small magnetic field of 100 Oe at room temperature. Which leads to an interesting increase in MR sensitivity about 2%/Oe. The main features of the magnetoresistive properties evolution with Cu deposition pressure are: The maximum of MR increases and moves towards larger Cu thicknesses (tCu) for increasing PCu. The saturation resistivity ρs decreases with increasing tCu while it increases versus PCu. The satisfactory agreement between our experimental results and calculated ones in the framework of the Johnson-Camley semi-classical model, allows us to interpret the MR and ρs behavior as a result of a reinforcement of the disordered phase ″CoZrCu″ inside the mixed zone whose thickness tmx increases with PCu . |
