Evolution of critical pressure with increasing Fe substitution in the heavy-fermion system ${URu}_{2 - x} {Fe}_{x} {Si}_{2}$

Journal Article Wolowiec, C. T. ; Kanchanavatee, N. ; Huang, K. ; ... - Physical Review B

Measurements of electrical resistivity, ρ(T ), were performed under quasihydrostatic pressure up to P ~ 2.2 GPa to determine the pressure dependence of the so-called hidden order (HO) and large-moment antiferromagnetic (LMAFM) phases for the URu_2-xFexSi2 system with x = 0.025, 0.05, 0.10, 0.15, and 0.20. As the Fe concentration (x) is increased, we observed that a smaller amount of external pressure, P_c, is required to induce the HO → LMAFM phase transition. A critical pressure of P_c ~ 1.2 GPa at x = 0.025 reduces to P_c ~ 0 at x = 0.15, suggesting the URu_2-xFe_xSi₂ system is fullymore »« less

Electronic structure of ${Ce}_{2} {RhIn}_{8}$ : A two-dimensional heavy-fermion system studied by angle-resolved photoemission spectroscopy

Journal Article Jiang, Rui ; Mou, Daixing ; Liu, Chang ; ... - Physical Review. B, Condensed Matter and Materials Physics

In this study, we use angle-resolved photoemission spectroscopy (ARPES) to study the two-dimensional (2D) heavy-fermion superconductor, Ce₂ RhIn₈. The Fermi surface is rather complicated and consists of several hole and electron pockets with one of the sheets displaying strong nesting properties with a q vector of (0.32, 0.32) π/a. We do not observe k_z dispersion of the Fermi sheets, which is consistent with the expected 2D character of the electronic structure. Comparison of the ARPES data to band-structure calculations suggests that a localized picture of the f electrons works best. While there is some agreement in the overall band dispersionmore »« less

Electronic structure of the quadrupolar ordered heavy-fermion compound ${YbRu}_{2} {Ge}_{2}$ measured by angle-resolved photoemission

Journal Article Pfau, H. ; Rosenberg, E. W. ; Massat, P. ; ... - Physical Review B

We studied the electronic structure of the heavy-fermion compound Yb(Ru_1–xRh_x)₂Ge₂ with x = 0 and nominally x = 0.125 using ARPES and LDA calculations. We find a valence band structure of Yb corresponding to a noninteger valence close to 3+. The three observed crystal electric field levels with a splitting of 32 and 75 meV confirm the suggested configuration with a quasiquartet ground state. The experimentally determined band structure of the conduction electrons with predominantly Ru 4d character is well reproduced by our calculations. YbRu₂Ge₂ undergoes a nonmagnetic phase transition into a ferroquadrupolar ordered state below 10.2 K and thenmore »« less
