Temperature Dependent 5f-states in URu2Si2
نویسنده
چکیده
A dramatic temperature dependent enhancement of U 5f spectral weight at EF is observed in angle-resolved photoemission measurements of URu2Si2 at the center of an X-point hole-pocket. Comparison of this temperature dependent behavior for excitation both at and below the U 5d→5f resonant threshold is presented.

Arrested Kondo effect and hidden order in URu2Si2
Complex electronic matter shows subtle forms of selforganization, which are almost invisible to the available experimental tools. One prominent example is provided by the heavy-fermion material URu2Si2. At high temperature, the 5f electrons of uranium carry a very large entropy. This entropy is released at 17.5 K by means of a second-order phase transition1 to a state that remains shrouded in m...
متن کاملSpectroscopic Determination of the Atomic f-Electron Symmetry Underlying Hidden Order in URu2Si2.
The low-temperature hidden-order state of URu2Si2 has long been a subject of intense speculation, and is thought to represent an as-yet-undetermined many-body quantum state not realized by other known materials. Here, x-ray absorption spectroscopy and high-resolution resonant inelastic x-ray scattering are used to observe electronic excitation spectra of URu2Si2, as a means to identify the degr...
متن کاملSinglet magnetism in heavy fermions.
We consider singlet magnetism for the uranium ions in UPt3 and URu2Si2 assuming that time-reversal symmetry is broken for the coherent state of intermediate valence. The relative weight of the two involved configurations should be different for UPt3 and URu2Si2. If in UPt3 the configuration 5f 1 on the U-ion prevails in the coherent state below the magnetic transition, the magnetic moment would...
متن کاملHoles in a Kondo lattice.
R eal metals invariably contain impurity atoms, and at concentrations of parts per million, nonmagnetic impurities have a barely detectable influence on the electronic properties of the vast majority of metals. On the other hand, pronounced changes can arise from magnetic impurities, such as iron impurity atoms in gold. At room temperature the magnetic moment carried by iron’s 3d electrons is d...
متن کاملInterplay between different states in heavy fermion physics
Calorimetry experiments under high pressure were used to clarify the interplay between different states such as superconductivity and antiferromagnetism in CeRhIn5, spin density wave and large moment antiferromagnetism in URu2Si2. Evidences are given on the re-entrance of antiferromagnetism under magnetic field in the superconducting phase of CeRhIn5 up to pc = 2.5 GPa where the Néel temperatur...
