Experimental results are presented for Rayleigh-Benard convection in thick horizontal layers of Homeotropic Nematic Liquid Crystal heated from below under external magnetic fields. New results are shown about the subcritical bifurcation in the oscillatory and steady convective regimes. Also, a more accurate estimation of the codimension-two point is made.

Abstract
Experimental results are presented for Rayleigh-Benard convection in thick horizontal layers of Homeotropic Nematic Liquid Crystal heated from below under external magnetic fields. New results are shown about the subcritical bifurcation in the oscillatory and steady convective regimes. Also, a more accurate estimation of the codimension-two point is made. The frequencies of the oscillatory solutions and other nonlinear effects are measured.File in questo prodotto:
