Research data for publication 'Ferroelectric nematic – isotropic liquid critical end point'

A critical end point above which an isotropic phase continuously evolves into a polar (ferroelectric) nematic phase with an increasing electric field is found in a ferroelectric nematic liquid crystalline material.Stored dataset includes files with results of (i) measurements of optical retardation vs. applied electric field, (ii) measurements of second harmonic generation activity vs. applied electric field, (iii) measurements of electric polarization by switching current method and (iv) published manuscript.
