复合体材料CuFe2O4－Pb（Mg1／3Nb2／3）O3的内耗和介电损耗
, PP. 1197-1200
Keywords: 磁电效应,内耗,介电常数
Abstract:
用传统的固相反应方法制备了CuFe2O4-Pb(Mg1／3Nb2／3)O3复合体材料陶瓷，用X射线衍射确定了复合体材料中各相的存在．用双端振动簧法研究了样品在-200—400℃的音频内耗谱，在37．6℃发现一个很大的内耗峰P1，并伴随着约9％的模量的软化，表明了相变的存在．在室温下，测量了介电常数ε′和介电损耗tanδ随频率变化的关系；同时，测量了复合体材料的介电常数和介电损耗随温度的变化关系，进一步验证P1峰由立方到四方的相变引起．最后给出样品的磁滞回线.
