摘要:

 通过溶胶–凝胶法在高致密度的钴铁氧体陶瓷片上制备锆钛酸铅(PZT)薄膜。在该复合结构中,PZT膜采用了较低的处理温度,从而有效避免了传统陶瓷共烧过程中出现的界面反应。样品表现出较好的铁电、介电、压电和磁电性能,并且面内磁电耦合系数可达58 mV/(cm?Oe)。

The lead zirconate titanate (PZT) thin films on the cobalt ferrite dense ceramics were prepared by a sol–gel method. In the composite structure, no interface reaction is detected due to the low-temperature sintering of the PZT film. The superior dielectric, ferroelectric and piezoelectric properties of the composite with a large magnetoelectric coefficient are obtained. The in-plane magnetoelectric coupling coefficient is 58 mV/(cm?Oe).
