In this CrystEngComm Hot article, (001)-oriented BaTiO3/LaNiO3 superlattics are made by a radio frequency sputtering method.
Liang Qiao and Xiaofang Bi noticed a dielectric anomaly in their superlattices; they observed that the dielectric maxima shifted towards higher temperatures with an increase in frequency. Read on to see how they explain their results, and to find out more about the dielectric properties and phase transition characteristics of their BaTiO3/LaNiO3 superlattices.
