“…Then vector is usually called the director of a sample. The largest eigenvalue of the order tensor Q ij is the second-rank order parameter P 2 [11][12][13][14][15] (0 < P 2 < 1). The calculated values P 2 = 0.69, 0.71, 0.60, 0.59 of the mesogenic layer at T = 250 K, 300 K, 350 K and 400 K, respectively was obtained (see Fig.…”
