Abstract
Magnetically induced birefringence measurements were performed in the isotropic phase of methoxybenzylidene butylaniline (MBBA). Over the entire temperature range studied, was found to be linear in to fields over 10 T. This result is consistent with the Landau model of the nematic-isotropic transition, and strongly inconsistent with the results of Keyes and Shane [Phys. Rev. Lett. 42, 722 (1979)] in a similar experiment. Their results indicate both the approach of a field-induced critical point and tricritical behavior near the phase transition.
