Values of the critical exponents for the order parameters (tilt angle and polarization P) and tilt angle susceptibility of C7 and of the (dielectric constant) of the mixture C7 + 10.O.4 close to are extracted from the power-law formula. Our results indicate a second-order and a weakly first-order Sm A - Sm C* transitions for C7 + 10.O.4 and C7, respectively as also observed experimentally.eninfo:eu-repo/semantics/closedAccessTilt angledielectric constantSm A - Sm C* transitionC7+10.O.4C7Article5541212910.1080/00150193.2019.1684762Q4WOS:0005158537000032-s2.0-85081057363Q4
