Research data for article 'Dielectric response of a ferroelectric nematic liquid crystalline phase in thin cells'

Dielectric properties of a polar nematic phase (NF) were studied for 3 homologues of a model ferronematogen, RM-734, differing in the length of the lateral chain. Measurements were performed for materials sandwiched between two gold or ITO electrodes, serving as a cell surfaces. Stored dataset contains files with numerical data for (i) complex permittivity measured vs. frequency and temperature (in some cases also bias voltage), (ii) optical retardance measured versus temperature, and (iii) images presenting optical textures of formed liquid crystalline phases taken with polarized-light optical microscope, (iv) graphical file (png) with molecular structure of studied compounds and their codes, (v) pdf file with published manuscript.
