The simultaneously measured ac susceptibility and static magnetization show neither evidence of the magnetic ordering, superconductivity down to the lowest temperatures nor conventional Landau Fermi-Liquid behavior. The results imply the magnetic transition temperature in undoped CeRu2Si2 is very close to absolute 0 K. The possibility for proximity of CeRu2Si2 to the quantum critical point without any doping is discussed., 金沢大学大学院自然科学研究科物理学, 金沢大学理学部}, pages = {180407-1--180407-4}, title = {ac susceptibility and static magnetization measurements of CeRu2Si2 at small magnetic fields and ultralow temperatures}, volume = {67}, year = {2003} }
