Abstract

In this letter the authors present the experimental data illustrating the working mechanism of the high sensitivity differential magnetic field sensor. Further, the authors report for the data showing the possibility for realizing a voltage controlled magnetic field. The sensor works on the following principle. A constant voltage is applied to the ring section of the sensor at the resonance frequency which induces magnetic field in the dot section. If an external magnetic object is brought in the vicinity of the dot section, then the resulting differential magnetic field induces change in the voltage gain due to magnetoelectric effect.
