Title: Coexisting spin resonance and long-range magnetic order of Eu in ${EuRbFe}_{4} {As}_{4}$

Abstract

Here, magnetic excitations and magnetic structure of EuRbFe₄As₄ were investigated by inelastic neutron scattering (INS), neutron diffraction, and random phase approximation (RPA) calculations. Below the superconducting transition temperature T_c=36.5 K, the INS spectra exhibit the neutron spin resonances at Q_res=1.27(2) and 1.79(3)Å^–1. They correspond to the Q=(0.5,0.5,1) and (0.5,0.5,3) nesting wave vectors, showing three-dimensional nature of the band structure. The characteristic energy of the neutron spin resonance is E_res=17.7(3) meV corresponding to 5.7(1)k_BT_c. Observation of the neutron spin resonance mode and our RPA calculations in conjunction with the recent optical conductivity measurements are indicative of the s± superconducting pairing symmetry in EuRbFe₄As₄. In addition to the neutron spin resonance mode, upon decreasing temperature below the magnetic transition temperature T_N=15 K, the spin wave excitation originating in the long-range magnetic order of the Eu sublattice was observed in the low-energy inelastic channel. Single-crystal neutron diffraction measurements demonstrate that the magnetic propagation vector of the Eu sublattice is k=(0,0,0.25), representing the three-dimensional antiferromagnetic order. Linear spin wave calculations assuming the obtained magnetic structure with the intra- and interplane nearest neighbor exchange couplings of J₁/k_B=–1.31 K and J_c/k_B=0.08 K can reproduce quantitatively the observed spin wave excitation. Our findings show that superconductivity andmore »« less

Spin excitations in optimally P-doped ${BaFe}_{2} {({As}_{0.7} P_{0.3})}_{2}$ superconductor

Journal Article Hu, Ding ; Yin, Zhiping ; Zhang, Wenliang ; ... - Physical Review B

We use inelastic neutron scattering to study temperature and energy dependence of spin excitations in optimally P-doped BaFe₂(As_0:7P_0:3)₂ superconductor (T_c = 30 K) throughout the Brillouin zone. In the undoped state, spin waves and paramagnetic spin excitations of BaFe₂As₂ stem from antiferromagnetic (AF) ordering wave vector QAF = ( 1; 0) and peaks near zone boundary at ( 1; 1) around 180 meV. Replacing 30% As by smaller P to induce superconductivity, low-energy spin excitations of BaFe₂(As_0:7P_0:3)₂ form a resonance in the superconducting state and high-energy spin excitations now peaks around 220 meV near ( 1; 1). These results aremore »« less

Complex magnetic properties in the mixed $4 f - 5 d$ double perovskite iridates $X_{2} {ZnIrO}_{6} (X = Nd, Sm, Eu, Gd)$

Journal Article Vogl, M. ; Morrow, R. ; Aczel, A. A. ; ... - Physical Review Materials

Here in this paper, we report on the synthesis and magnetic properties of a series of double perovskites Ln₂ZnIrO₆ with Ln = Nd, Sm, Eu, Gd. These compounds present examples of the rare case of double perovskites (general formula A₂BB'O6) with a magnetic 4ƒ-ion on the A site in combination with the strongly spin-orbit coupled 5d transition-metal ion Ir⁴⁺ on the B sublattice. We discuss the impact of different rare earths on the macroscopic magnetic properties. Gd₂ZnIrO₆ and Eu₂ZnIrO₆ show ferrimagnetic or canted antiferromagnetic order below T_N = 23 and 12 K, respectively. Sm₂ZnIrO₆ orders antiferromagnetically at T_N = 13more »« less

Unusual Dynamic Charge Correlations in Simple-Tetragonal ${HgBa}_{2} {CuO}_{4 + δ}$

Journal Article Yu, B. ; Tabis, W. ; Bialo, I. ; ... - Physical Review. X

The charge-density-wave (CDW) instability in the underdoped, pseudogap part of the cuprate phase diagram has been a major recent research focus, yet measurements of dynamic, energy-resolved charge correlations are still in their infancy. Such information is crucial in order to help discern the connection between CDW and pseudogap phenomena, and to understand the extent to which charge correlations in general shape the phase diagram. We report a resonant inelastic x-ray scattering study of the underdoped cuprate superconductor HgBa₂CuO_4+δ (T_c = 70 K). At 250 K, above the previously established temperature T_CDW ≈ 200 K that signifies the onset of quasistaticmore »« less

Origin of magnetic excitation gap in double perovskite ${Sr}_{2} {FeOsO}_{6}$

Journal Article Taylor, Alice E. ; Morrow, Ryan ; Lumsden, Mark D. ; ... - Physical Review B

Sr₂FeOsO₆ is an insulating double perovskite compound which undergoes antiferromagnetic transitions at 140 (T_N1) and 67 K (T_N2). To study the underlying electronic and magnetic interactions giving rise to this behavior we have performed inelastic neutron scattering (INS) and resonant inelastic x-ray scattering (RIXS) experiments on polycrystalline samples of Sr₂FeOsO₆. The INS data reveal that the spectrum of spin excitations remains ungapped below T_N1, however below T_N2 a gap of 6.8 meV develops. The RIXS data reveals splitting of the T_2g multiplet consistent with that seen in other 5d³ osmium based double perovskites. Altogether these results suggest that spin-orbit couplingmore »« less
