    Abstract

    The high-quality magnetic fluid composition is capable of forming two-dimensional lattices of concentrated magnetic particle columns in a thin film in magnetic fields. The extraordinary lattices, a kind of novel mesoscopic system, have been explored with optical microscopy, digital imaging, and computer-video technique in this study. The two-dimensional lattices present hexagonal phase with exotic topological defects due to the structure distortion under excitations. The ordering of the 2D lattices are classified with positional and bond-orientational correlation functions. Some dynamical observations of topological defects are also made in this study.
