摘要:
研究了Terfenol-D(TDF)/Pb(Zr,Ti)O3(PZT)三明治结构的磁电容效应.由于磁-力-电耦合机制,PZT受由磁场引起的应力作用,产生磁电容.结果显示,在偏置磁场1 600 Oe、谐振频率46.15 kHz和160.00 kHz处,最大负磁电容分别可达65%和85%,在非谐振频率处负磁电容仅为5%.
Abstract:
The presen t work is focused on the g iant room??temperature m agne to??capacitance (MC) e ffect in lam inate o f TerfenolD( TDF) /Pb( Zr, T i) O3 ( PZT ) composites. Such m agne to??capac itance re la tes to the m agnetic??e lastic coupling of interfaces. Them ax imum negative m agneto??capac itance is as large as 65% and 85% at the resonant frequencies o f 46.15 kH z and 1600 OekH z, respectiv ely, under the b ias m agnetic fie ld of 1600 Oe. A nega tivem agneto??capacitance o f 5% has been observed at sub??resonan t frequenc ies under the same m agnetic field
