Optimized anisotropic magnetoelectric response of Fe61.6Co16.4Si10.8B11.2/PVDF/Fe61.6Co16.4Si10.8B11.2 laminates for AC/DC magnetic field sensing

Abstract

Anisotropic magnetoelectric (ME) effect on a Fe61.6Co16.4Si10.8B11.2/PVDF Fe61.6Co16.4Si10.8B11.2laminate composite has been used for the development of a magnetic field sensor able to detect both magnitude and direction of AC and DC magnetic fields. Accuracy (99% for both AC and DC sensors), linearity (92% for the DC sensor and 99% for the AC sensor) and reproducibility (99% for both sensors) indicate the suitability of the sensor for applications. Further, the sensitivity of the Fe61.6Co16.4Si10.8B11.2/PVDF/ Fe61.6Co16.4Si10.8B11.2 anisotropic magnetic sensor, 15 and 1400 mV.Oe-1 for DC and AC fields, respectively, are the highest reported in the literature for polymer-based ME materials . Such features allied to the flexibility, versatility, lightweight, low cost and low-temperature fabrication lead to the suitability of the developed sensor for magnetic sensor applications.
