Description

The folder includes generated data MATLAB scripts to read/plot the polarization-electric field (PE) hysteresis curves. The dataset contains phase field generated polycrystalline grain structure, simulated domain structures during polarization reversal, and symmetric PE curves (measured and simulated).

Polycrystalline grain structures: The output files are in the *.txt format, readable by MTEX to generate orientation maps.
