Quantized electronic fine structure with large anisotropy in ferromagnetic Fe films
C. Seibel, A. Nuber, H. Bentmann +4
We report on the spectroscopic observation of a quantized electronic fine structure near the Fermi energy in thin Fe films grown on W(110). The quantum well states are detected dow…
Momentum-resolved evolution of the Kondo lattice into 'hidden-order' in URu2Si2
F. L. Boariu, C. Bareille, H. Schwab +5
We study, using high-resolution angle-resolved photoemission spectroscopy, the evolution of the electronic structure in URu2Si2 at the Gamma, Z and X high-symmetry points from the…
Coherent heavy quasiparticles in CePt5 surface alloy
M. Klein, A. Nuber, H. Schwab +9
We report on the results of a high-resolution angle-resolved photoemission (ARPES) study on the ordered surface alloy CePt5. The temperature dependence of the spectra show the form…
High-temperature signatures of quantum criticality in heavy fermion systems
J. Kroha, M. Klein, A. Nuber +3
We propose a new criterion for distinguishing the Hertz-Millis (HM) and the local quantum critical (LQC) mechanism in heavy fermion systems with a magnetic quantum phase transition…
Fermi surface instability at the hidden-order transition of URu2Si2
A. F. Santander-Syro, M. Klein, F. L. Boariu +3
Solids with strong electron correlations generally develop exotic phases of electron matter at low temperatures. Among such systems, the heavy-fermion semi-metal URu2Si2 presents a…
Signature of quantum criticality in photoemission spectroscopy at elevated temperature
M. Klein, A. Nuber, F. Reinert +3
A quantum phase transition (QPT) in a heavy-fermion (HF) compound may destroy the Fermi liquid groundstate. However, the conditions for this breakdown have remained obscure. We rep…
