摘要

采用阻抗谱法研究了单晶磁电铋铁氧体BiFeO3的电导率和介电常数随温度变化的阻抗谱。BiFeO3是一种很有前途的RAM功能材料。在交流条件下，确定了多铁结构载流子低温（110 ~ 300 K）运动过程的活化能，以及这些过程之间的临界温度与频率的对数关系。结果表明，在该温度范围内，BiFeO3晶格参数的低温活化与交流特性有一定的相关性。

Frequency-Dependent Temperature Activation of Conductivity and Dielectric Constant of Magnetoelectric BiFeO3

We presented the research results by impedance spectroscopy of frequency-dependent temperature activation of the conductivity and dielectric constant of the single-crystal magnetoelectric bismuth ferrite BiFeO₃, a promising functional material for RAM devices. The activation energies of low-temperature (110–300 K) processes of motion of charge carriers of the multiferroic structure and the logarithmic dependence of the critical temperatures between these processes on the frequency are determined in AC regime. It has been established that in this temperature range there is a correlation of AC characteristics with low- to high-temperature activation of the parameters of the BiFeO₃ crystal lattice.
