Paranematic susceptibility

Paranematic susceptibility refers to the response of a nematic liquid crystal to an external electric or magnetic field, particularly in terms of its alignment or orientation. In the context of liquid crystals, "paranematic" generally refers to a state where the liquid crystal molecules are predominantly aligned in a certain direction but not as ordered as in a fully nematic phase. The susceptibility aspect indicates how much the orientation of the liquid crystal is affected by the external field.
