磁电效应是施加磁场产生电极化的物理效应,动态法测量磁电转换系数,是测量磁电材料的磁电效应的一类主要方法。本文尝试设计了一种屏蔽线圈式的微型磁电测; 试方法,改变了以往的电磁屏蔽方式,从屏蔽样品改为屏蔽线圈,并采用单线圈的设计,从而扩大了样品空间,提供一种可以微型化,便于嵌入低温系统的动态法磁; 电效应测试方法。Magnetoelectric effect is the effect that applied magnetic field induces; an electric polarization. The dynamic method is the main test method of; magnetoelectric coefficient. Here, this article attempted to design a; miniature test system by shielding coil. In this design, shielding; method was changed from sample-shielding to coil-shielding and the coil; was changed from dual-coils to single-coil. After changing, the sample; space is enh anced obviously, while the test system size is very small.; This study provides a miniature dynamic magnetoelectric test method; which can be easily embedded into general cryogenic system.
