The interplay between charge-density waves (CDW) and other ordered states in intermetallic materials remains an intriguing question in condensed matter physics. For example, despite the many low-dimensional examples, the role of CDW and its relationship with the superconducting state for three-dimensional compounds has yet to be completely unraveled. In this talk, we present experimental X-ray diffraction and electrical resistivity studies on some single-crystalline intermetallic compounds to explore the charge-ordered phase in these materials.
