High‐energy synchrotron X‐ray diffraction experiments were performed for clathrate‐forming barium–germanium (Ba–Ge) alloys in the liquid state near the eutectic composition. The accurate structure information of highly reactive melts has been obtained by applying electrostatic levitation technique as a containerless method. The structure information obtained from the reverse Monte Carlo simulation suggests that the short‐range ordering between the Ge atoms occurs with the addition of Ba atoms in the liquid Ba–Ge alloys. This can be associated with the formation of the cage‐like structure composed of the Ge atoms in the liquid alloys near the eutectic composition.
