The structure of disordered materials such as glasses and liquids is usually analyzed by the X-ray diffraction and obtained pair distribution functions are used in the structural discussion. This function corresponds to the probability of finding another atom at a distance r from the origin atom and careful analysis allows us to obtain the local structural image by estimating inter-atomic distances and corresponding coordination numbers at near neighbor region. However, recent structural studies of non-crystalline materials require the information covering middle range structure so as to discuss physico-chemical properties such as crystallization procedure. The reverse Monte Carlo (RMC) simulation technique is one way to obtain such middle range structure and present paper demonstrates a couple of structural studies analyzed by X-ray scattering coupled with RMC simulation method.
