We report on the dependence of the converse magnetoelectric effect (CME) on the composition of Co60Fe20B20, Co43Fe43B14 and Co28Fe52B20 soft magnetic layers when coupled with PZT-micro-fiber-composites (MFC). In all cases we show strong CME responses, with squareness reduction of 60−80% when increasing the E-field from −1 to +1.4 MV/m. The highest CME response is found for Co43Fe43B14 which shows the largest ratio between the magnetostriction coefficient λs and the saturation magnetization Ms among the three compositions. According to the quasi-static magnetoelectric converse theory, the linear coupling factor α up to 1.65 µs/m and voltage coefficient MEH up to 250 V·cm−1·Oe−1 are calculated, which is 2−3 orders of magnitude higher than usually reported.
