It is found that the ordering is associated with the onset of a low temperature insulator phase. These conclusions are supported by the facts that the space group of the crystal structure transforms from Im3¯ to Pm3¯ below the M-I transition temperature and also that the temperature dependence of the superlattice peaks in the insulator phase follows the squared BCS function. The M-I transition could be originated from the perfect nesting of the Fermi surface and/or the instability of the f electrons}, pages = {153105-1--153105-4}, title = {Charge-density-wave ordering in the metal-insulator transition compound PrRu4P12}, volume = {70}, year = {2004}, yomi = {セキネ, チヒロ and キホウ, クニヒロ and シロタニ, イチミン} }
