“…16 show that near the tricritical point the latent heat along the first-order part of the NA line has a nearly quadratic dependence on concentration which crosses over to a nearly linear dependence far away from that point. 104 This is not in agreement with mean-field Landau theory without a cubic term, where it is predicted that the latent heat along the first-order side of the transition line should be a linear function of the distance from the tricritical point, i.e. in a mixture one should have: AH\, ~ (x -x'), with x' the tricritical concentration.…”

“…Although the Mc Millan ratio M ¼ T NA /T NI where T NA and T NI are the N-Sm A and N-I transition temperatures, respectively, is a measure of the proximity of the N-Sm A transition to the N-I transition (35), namely the width of the nematic range, its value is not universal for different systems. Tricritical points in previously studied systems are characterized by McMillan ratios of 0.942 to 0.995 (18,23,31,(36)(37)(38)(39), and systems with smaller ratios usually exhibit second order N-Sm A transitions (28).…”
