Fig 3: The nmr microimages obtained with the different currents (I=0.8 A-5.6 A) and PGSE sequence with delta=1 ms and Delta=3.6 ms respectively. The increasing current expands the region with the shape of butterfly wings which due to anisotropic spin echo attenuation in liquid crystal.

Fig. 4: Basic equations of anisotropic spin echo attenuation together with a schematic representation of the lamellar phase in a AOT[bis(2-ethylhexyl) sodium sulfosuccinate]/water in which the lamelae are presumed to be concentic cylinders aligned parallel to the surface, thus enabling free azimuthal diffusion and hindered radial diffusion. Calculated echo amplitude is based on a diffusion anisotropy (DII/Dp) of 20.
