Large unconventional anomalous Hall effect far above room temperature in epitaxial Fe3Ga4 films

Crystal structure and characterizations of Fe₃Ga₄ films

The epitaxial nature of the sputtered Fe₃Ga₄ film was checked by x-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements. Figure 1b shows a representative 2θ–ω…
