Paranematic susceptibility

In the study of liquid crystals the paranematic susceptibility (latin: susceptibilis “receptiveness”) describes the degree of induced order in a liquid crystal in response to an applied magnetic field. The paranematic suceptibility is often given by:

$/eta={\frac {\Delta \chi _{max}V}{3k_{B}T}}\langle |S(\mathbf {q} =0|^{2}\rangle$
