Abstract
Normally 4-methoxybenzylidene-4′-n-butylaniline exhibits only one liquid-crystalline phase; it is nematic at room temperature. However, after quenching it at liquid nitrogen temperature it is possible to reach four new phases by successive annealing. We report here an experiment aimed at providing a better understanding of these phases by studying their texture after quenching in a magnetic field large enough to orient the sample in the nematic phase.
