FIG. 1.

(Color online) (a) θ − 2θ x-ray diffraction scan of Co2MnAl deposited at 688 °C on MgO. Inset left shows the corresponding phi-scan of four equivalent (111) reflections. (b) Saturation magnetization for samples deposited at different T d .

FIG. 2.

(Color online) The legends on (a) and (c) are also valid for (b) and (d), respectively. (a) Hall data at T = 5 K for samples deposited at different temperatures under “clean” conditions onto MgO (100). (b) Linearity of the signal in (a) normalized to initial slope. (c) Hall measurements performed at different temperatures on samples deposited at room temperature onto Si (100) under “dirty” conditions. (d) Linearity of the signal in (c) normalized to initial slope. (e) and (f) Hall effect measurements performed in an electromagnet at different temperatures on a sample deposited at 530 °C (RT) in clean (dirty) conditions. Inset in (b) shows an AFM picture of sample deposited at 648 °C in clean conditions. Inset in (d) shows Hall bar with an effective area of 8 × 3 mm2.

FIG. 3.

(Color online) (a) and (b) Photoelectron emission spectra in the range of O1s peak and valence states, respectively. The measurements were performed at 19 °C with an excitation energy of 1486.6 eV.
