Fig. 1

a Schematic illustration of the magnetic heterostructures, side-view of the magnetron sputtering chamber and the Hall bar device arrangement on the sample holder. The dotted arrow represents the Pt atom flow from the target immediately below the wedge-shaped holder with a tilting angle (\({\theta }_{{\rm{dep}}}\)). b, c The anomalous Hall effect (AHE) hysteresis loops and the corresponding coercivity (\({H}_{{\rm{c}}}\)) and the degree of perpendicular anisotropy (\({M}_{{\rm{r}}}/{M}_{{\rm{s}}}\)) of the devices prepared by different \({\theta }_{{\rm{dep}}}\).
