Figure 3.

(a) Schematic of the cantilever-type magnetometer using inversed deposition sequence; (b) measured ME voltage coefficient as a function of the frequency of the applied AC magnetic field. The sharp peak marks the mechanical resonant frequency of 867 Hz. The inset shows the ME voltage coefficient above the resonance; (c) measured voltage noise density with respect to the magnitude of applied AC magnetic field with constant frequency of 867 Hz; and (d) measured voltage noise density with respect to the frequency of applied AC magnetic field with constant magnitude of 1 × 10⁻³ Oe.
