FIG. 1.

Extraordinary Hall effect measurements as a function of the applied magnetic field recorded at room temperature for samples with different oxidation times: varying from for (a) and for (b).

FIG. 2.

(-☉-) Coercive field (left axis) and (-▴-) tunnel magnetoresistance (right axis) as a function the oxidation time both recorded at room temperature. Inset: Resistance vs applied magnetic field of a MTJ with an Al layer oxidized for .

FIG. 3.

(a) Co XPS spectra corresponding to an oxidation of recorded after different etching times. The gray plots are Co and Co oxide reference spectra. (b) Area of Al oxide and Co levels vs etching time. Each vertical gray line corresponds to an etching time after which XPS spectra presented in (a) are recorded.

FIG. 4.

(Color online) Resistance vs applied field recorded at room temperature. Inset: zoom in on the low field region.
