摘要:
研究了压电/压磁条环磁电复合材料在弯曲谐振频率下的逆磁电效应(CME),其中压电材料为锆钛酸铅(PZT),压磁材料为镍锌铁氧体(NiZn ferrite). 由于PZT与镍锌铁氧体环之间的机电耦合,该磁电材料在一阶弯曲谐振频率和一阶纵向谐振频率处的逆磁电系数明显大于非谐振频率处的逆磁电系数. 在一阶弯曲谐振频率下,该磁电材料在H=190 Oe、E=200 V/cm测得较大磁感应强度(Bm≈2.13×10-5 G). Bm在-130
Abstract:
Converse magnetoelectric effect(CME)is investigated in a strip-ring magnetoelectric composite of ferrite-lead zirconate titanate(PZT)and nickel-zinc(Ni-Zn)ferrite at the bending mode resonance frequency. Due to the electromechanical coupling,the composite shows higher CME coefficients at the first bending and second longitudinal modes resonance frequencies than at the non-resonance frequencies. At the first bending mode resonance frequency,a peak value of the magnetic induction(Bm≈ 2.13×10-5 G)is measured at H=190 Oe and E=200 V/m. The hysteresis behavior of Bm is shown at -130 Oe<H<130 Oe,which is attributed to the combination of the piezomagnetic efficient of Ni-Zn ferrite and the ferroelastic effect of PZT. At H=0 Oe,±50 Oe,three stable magnetic induction states are obtained by periodically applying alternating signal with different trends of the magnetic field.
