TL;DR: This work demonstrates that a single experimental parameter, strain, simultaneously controls multiple order parameters and is a viable alternative tuning parameter to composition for creating multiferroics.

TL;DR: The magnetodielectric effect is caused by the combination of magnetoresistance and the Maxwell-Wagner effect, as predicted by Catalan [Appl. Phys. Lett. 88, 102902 as mentioned in this paper.

TL;DR: In this article, a theory is suggested which assumes a frozen dipole moment connected with the grain boundaries which induces the polar phase in the grain bulk in correlation with the bulk soft-mode frequency.

TL;DR: In this unique system an increase in the separation between the (SrO)2 planes, which can be achieved by changing n, bolsters the local ferroelectric instability and can be exploited to achieve a figure of merit at room temperature that rivals all known tunable microwave dielectrics.

TL;DR: In this article, the complex dielectric response of cubic pyrochlore ceramics was investigated between 100 Hz and 100 THz by a combination of low-frequency capacitance bridges, a high-frequency coaxial technique, time domain transmission THz spectroscopy, and infrared spectrographs.
