概要:

金沢大学大学院自然科学研究科物理学<br />金沢大学理学部<br />The magnetic properties of CeRu2Si2 at microkelvin temperatures (down to 170 μK) and ultrasmall magnetic fields (0.02∼6.21 mT) are investigated experimentally. The simultaneously measur … ed 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. 続きを見る
