In the basic science field revealing new properties and functions of materials, it is necessary to investigate phase transitions on environmental change like temperature variation. Phase transitions of magnetic state and electrical conductivity accompany often transformations of crystal structures or atomic arrangements. In present study on dynamical behaviors of the material structures, the physical mechanisms of electronic and structural phase transitions was investigated for the compounds with strongly hybridized electrons between rare-earth elements and neighboring atoms.
