We present the first experimental results on the molecular orientation of LC monolayers in high magnetic fields. The influence of the external magnetic field on the in-plane molecular orientation of 4-n-octyl-4′-cyanobiphenyl (8CB) molecules on rubbed polymer surfaces is studied with the use of second-harmonic generation. It is found that the orientation of the LC molecules is fixed with respect to the rubbing axis upto magnetic fields of 20 T. These results are in-line with the previously proposed model for surface-induced LC alignment based on a LC bulk interacting with a fixed interfacial LC monolayer. It can also be concluded that hardly any collective behaviour of the LC molecules, constituting the first monolayer, is present.
