A Magentoelectric Coefficient Measurement System with a Free-Stress Sample Holder

Abstract: With less extra stress on the testing sample, a free-stress sample holder was designed to place the sample horizontally. With the free-stress sample holder, a magnetoelectric (ME) coefficient measurement system was developed based on dynamic method. This measurement system has the hardware part and the software part, integrated by the DC magnetic field generation module, the AC magnetic field generation module, the induced ME voltage detecting module and PC software module. Then, a sample of Terfenol-D/PZT/Ter… Show more

“…At low DC fields (up to 0.14 T) there is a linear increase of U OUT relative to H DC . Next, the voltage reaches some maximum value and then gradually decreases between 0.34 and 0.45 T. The observed trend corresponds well to published data for PZT/Terfenol-D composites [13,22,23,25,29,30]. The shape of characteristics is related to the dependence of the magnetostrictive coefficient of Terfenol-D on the DC magnetic field, as shown in [22,29,31].…”

“…All peaks for various DC fields occur at approximately the same frequencies. In comparison to the data published for composites, in which the authors observe one or two separated peaks [12,13,22,23,[27][28][29][30], we detect multiple, overlapping resonant peaks (60-80 kHz range). The existence of resonant peaks shown in Figure 4 may be explained by the structure of the S1 composite.…”
