英文摘要
We have obtained, for the first time, microscopic evidence that weak antiferromagnetism of the 5f-electron superconductor URu_2Si_2 is ascribed to an inhomogeneous antiferromagetic order induced by a residual stress in a crystal. We have further shown that the superconductivity of this system does not coexist with the antiferromagnetism but does occur only in the unknown ordered state called "hidden order". Some new findings have also been obtained from the study of related materials, regarding electronic properties in the vicinity of quantum phase transitions and magnetism of 5f-electron systems.
