We show how the degree of impenetrability of dielectric inclusions plays a substantial role in controlling the coercive field, remnant and saturation polarizations of the homogenized materials. The results highlight the significance of the degree of impenetrability of inclusion in tuning the effective polarization properties of such ferroelectric composites: coercive field drops significantly as percolation threshold is attained and remnant polarization decreases faster than a linear decay. https://ris.uni-paderborn.de/download/52700/52701/2024-03 Myroshnychenko - Physica Scripta - From Swiss-cheese to discrete ferroelectric.pdf application/pdfno IOP Publishing2024 eng tet_topic_ferro 0031-8949 1402-489610.1088/1402-4896/ad3172 994045952 @article{Myroshnychenko_Mulavarickal Jose_Farheen_Ejaz_Brosseau_Förstner_2024, title={From Swiss-cheese to discrete ferroelectric composites: assessing the ferroelectric butterfly shape in polarization loops}, volume={99}, DOI={<a href="https://doi.org/10.1088/1402-4896/ad3172">10.1088/1402-4896/ad3172</a>}, number={4}, journal={Physica Scripta}, publisher={IOP Publishing}, author={Myroshnychenko, Viktor and Mulavarickal Jose, Pious Mathews and Farheen, Henna and Ejaz, Shafaq and Brosseau, Christian and Förstner, Jens}, year={2024}, pages={045952} } Myroshnychenko V, Mulavarickal Jose PM, Farheen H, Ejaz S, Brosseau C, Förstner J.
