GAO Qiu-ling, LI Ping. Study on magnetoelectric effect of ferromagnetic alloy/piezoelectric composite material[J]. 2010, 29(1): 62-64+68. DOI: 10.13873/j.1000-97872010.01.005.
A FeNi-based spring alloy/piezoelectric magneto-electrical composite material has been developed by the high mechanical quality factor of the FeNi-based spring alloy.Based on the equivalent circuit method
the relation between magneto-electric voltage coefficient
resonance frequency
mechanical quality factor
the maximal output power and the length ratio of magneto-strictive to piezoelectric layer is analyzed.Theoretical analysis and the experimental results indicate with increasing the length of FeNi-based spring alloy
the magneto-electric voltage coefficient
mechanical quality factor and the maximal output power increase and tend to constant
