Ultrasonic study of the hidden order and heavy-fermion state in URu2Si2 with hydrostatic pressure, Rh-doping, and high magnetic fields
Abstract
This paper reports recent progress of ultrasonic measurements on URu?Si?, including ultrasonic measurements under hydrostatic pressure, in pulsed magnetic fields, and the effect of Rh-substitution. The observed changes of the elastic responses shed light on the orthorhombic-lattice instability with ?-symmetry existing within the hidden order and the hybridized 5?-electron states of URu?Si?.
