Abstract
Highly sensitive optical reflectivity measurements are used to investi gate the layer-by-layer transition in extremely thin and thick N-(4-n- hexyloxybenzylidene)-4-n-hexylaniline (60.6) films. The simple power-l aw form, N=N(0)t(-1/3), for the penetration of the crystal-B order is found to describe the transitions only near the surface. A deviation f rom the power law is observed for the interior layers. (C) 1996 Americ an Institute of Physics.
