Abstract

The magnetoelectric sensor based on (Fe80Co20)78Si12B10/PZT laminates is designed, fabricated and characterized for determining dc and ac magnetic-field strengths as well as field orientations. At low dc magnetic-fields, a ME-voltage response (dVME/dH) as high as 2 mV/Oe is achieved. The linear relation VME(hac) with a slope of dVME/dhac of 17 mV/Oe shows a great ability to self-powered detecting low ac magnetic-fields. The field orientation can be detected by using the sinusoidal dependence of the magnetoelectric voltage. The sensor is promising not only for microtesla magnetic-field sensing but also for magnetic biosensor applications.
