Title: Distinct magnetic spectra in the hidden order and antiferromagnetic phases in ${URu}_{2 - x} {Fe}_{x} {Si}_{2}$

Abstract

We use neutron scattering to compare the magnetic excitations in the hidden order (HO) and antiferromagnetic (AFM) phases in URu_2–xFe_xSi₂ as a function of Fe concentration. The magnetic excitation spectra change significantly between x=0.05 and x=0.10, following the enhancement of the AFM ordered moment, in good analogy to the behavior of the parent compound under applied pressure. Prominent lattice-commensurate low-energy excitations characteristic of the HO phase vanish in the AFM phase. The magnetic scattering is dominated by strong excitations along the Brillouin zone edges, underscoring the important role of electron hybridization to both HO and AFM phases and the similarity of the underlying electronic structure. As a result, the stability of the AFM phase is correlated with enhanced local-itinerant electron hybridization.

Analogy Between the “Hidden Order” and the Orbital Antiferromagnetism in ${URu}_{2 - x} {Fe}_{x} {Si}_{2}$

Journal Article Kung, H.-H. ; Ran, S. ; Kanchanavatee, N. ; ... - Physical Review Letters

We study URu_2-xFe_xSi₂, in which two types of staggered phases compete at low temperature as the iron concentration x is varied: the nonmagnetic \hidden order" (HO) phase below the critical concentration x_c, and unconventional antiferromagnetic (AF) phase above x_c. By using polarization resolved Raman spectroscopy, we detect a collective mode of pseudovector-like A_{2_g} symmetry whose energy continuously evolves with increasing x; it monotonically decreases in the HO phase until it vanishes at x = x_c, and then reappears with increasing energy in the AF phase. The mode's evolution provides direct evidence for unified order parameter for both nonmagnetic and magneticmore »« less

Quasiparticle relaxation dynamics in ${URu}_{2 - x} {Fe}_{x} {Si}_{2}$ single crystals

Journal Article Kissin, Peter ; Ran, Sheng ; Lovinger, Dylan ; ... - Physical Review B

We investigate quasiparticle relaxation dynamics in URu_2–xFe_xSi₂ single crystals using ultrafast optical-pump optical-probe (OPOP) spectroscopy as a function of temperature and Fe substitution (x), crossing from the hidden-order (HO) phase (x = 0) to the large-moment antiferromagnet (LMAFM) phase (x = 0 .12). Here, at low temperature, the dynamics for x = 0 and x = 0 .12 are consistent with the low-energy electronic structure of the HO and LMAFM phases that emerge from the high-temperature paramagnetic (PM) phase. In contrast, near the bicritical point separating HO and LMAFM (x = 0 .1), two transitions occur over a narrow temperaturemore »« less

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

Here, we present data on the optical conductivity of URu_2-x(Fe,Os)_xSi₂. While the parent material URu₂Si₂ enters the enigmatic hidden order (HO) phase below 17.5 K, an antiferromagnetic (AFM) phase is induced by the substitution of Fe or Os onto the Ru sites. We find that both the HO and the AFM phases exhibit an identical gap structure that is characterized by a loss of conductivity below the gap energy with spectral weight transferred to a narrow frequency region just above the gap, the typical optical signature of a density wave. The AFM phase is marked by strong increases in bothmore »« less

Non-Fermi-liquid types of behavior associated with a magnetic quantum critical point in $Sr {({Co}_{1 - x} {Ni}_{x})}_{2} {As}_{2}$ single crystals

Journal Article Sangeetha, N. S. ; Wang, L. -L. ; Smirnov, A. V. ; ... - Physical Review B

The compound SrCo₂As₂ with the body-centered tetragonal ThCr₂Si₂ structure is known to remain paramagnetic down to a temperature T = 0.05 K, but inelastic neutron scattering studies have shown that both ferromagnetic (FM) and antiferromagnetic (AFM) fluctuations occur in single crystals. Thus it is of interest to study how the magnetism evolves on doping SrCo₂As₂. Previous work on polycrystalline samples of Sr (Co_1-x Ni_x)₂ As₂ indicated the development of AFM order for 0 < x ≲ 0.3. Here we studied single crystals of Sr(Co_1-x Ni_x)₂ As₂ for 0 < x ≤ 1 and confirmed the occurrence of AFM order whichmore »« less
