(a) Schematic cross section and top view (not to scale) of the realized devices. The magnetic induction is applied: (b) out-of-plane, (c) in-plane at 45°.
SEM images: (a) complete device, (b) “open” device. AFM images (intensity scale ): (c) complete device, (d) “open” device.
Hall voltage as a function of the out-of-plane magnetic induction.
Magnetic field resolution as a function of frequency.
Hall voltage as a function of the in-plane magnetic induction. Only a few devices show this behavior.
