Dataset description

The dataset contains spontaneous polarisation data for the ferroelectric nematic liquid crystal, FNLC-919. The tests are done using the current reversal technique (as described by Miyasato et al. in 1983) which gives values of polarisation when a voltage is applied to a sample, so the data mainly consists of polarisation values for the samples taken at a range of voltages. Tests were done to check the polarisation response in four different thicknesses (4, 10, 23, and 46 microns) as well as to check the longevity of a sample when preparation conditions were varied (i.e. if it was prepared in the polar (ferroelectric nematic) phase or one of the nonpolar phases (nematic or isotropic)).
