Insights into the dielectric response of ferroelectric relaxors from statistical modeling, J. Liu, F. Li, Y. Zeng, Z. Jiang, L. Liu, D. Wang, Z.-G. Ye, and C.-L. Jia Phys. Rev. B 96, 054115

Figure 1. — Relaxors are interesting ferroelectric materials. To understand how they evolve with temperature, we propose special equations to fitted the “dielectric constant vs temperature” data, which turns out to be quite successful.

If you are interested, here we also provide the data and the Mathematica program so that you can try it for yourself – just put the two files in the same directory, then start the Mathematica program.
