Magnetic-field induced isotropic to nematic liquid crystal phase transition

T Ostapenko, DB Wiant, SN Sprunt, A Jákli… - Physical review letters, 2008 - APS
We report on measurements of magnetic-field induced nematic order in the bent-core liquid
crystal<? format?> 4-chlororesorcinol bis [4-(4-n-dodecyloxybenzoyloxy) benzoate]. Using
the 31 T solenoid at the National High Magnetic Field Laboratory, we have observed, at
temperatures less than 1° above the clearing point, a first-order transition to the nematic
phase. The critical magnetic field at which this occurs increases with temperature. We
discuss these results within the context of both Maier-Saupe and Landau–de Gennes mean …

Magnetic-field induced isotropic to nematic liquid crystal phase transition

JT Gleeson, TB Ostapenko, DB Wiant… - APS March Meeting …, 2009 - ui.adsabs.harvard.edu
We report on measurements of magnetic field induced nematic order in the bent-core liquid
crystal 4-chlororesorcinol bis [4-(4-n-dodecyloxybenzoyloxy) benzoate]. Using the 31 Tesla
solenoid at the National High Magnetic Field Laboratory, we have observed, at temperatures
less than one degree above the clearing point, a first-order transition to the nematic phase.
The critical magnetic field at which this occurs increases with temperature. We discuss these
results within the context of both Maier-Saupe and Landau-deGennes mean field models for …
