Common origin of the two types of magnetic fluctuations in iron chalcogenides

Journal Article Singh, D K - Physical Review. B, Condensed Matter and Materials Physics

We use inelastic neutron scattering to study the low-energy spin excitations in moderately doped nonsuperconducting Fe{sub 1.01}Te{sub 0.72}Se{sub 0.28}. The spin excitations in this system contain components near (0.5,0,0) and (0.5,0.5,0) in a-b plane reciprocal lattice units using tetragonal unit cell notation (a = b = 3.772 {angstrom} and c = 6.061 {angstrom}). At low energies the scattering is centered around (0.5,0,0). With increasing energy, the spectral weight of low-energy spin excitations centered around (0.5,0,0) abruptly shifts around 3 meV to the incommensurate spin excitations centered around (0.5,0.5,0). However both types of spin fluctuations exhibit the identical temperature dependence. Thesemore »« less
Ferro-Orbital Order and Strong Magnetic Anisotropy in the Parent Compounds of Iron-Pnictide Superconductors

Journal Article Lee, C C ; Yin, W -G ; Ku, W - Physical Review Letters

The puzzling nature of magnetic and lattice phase transitions of iron pnictides is investigated via a first-principles Wannier function analysis of representative parent compound LaOFeAs. A rare ferro-orbital ordering is found to give rise to the recently observed highly anisotropic magnetic coupling, and drive both phase transitions - without resorting to widely employed frustration or nesting picture. The revealed necessity of the additional orbital physics leads to a correlated electronic structure fundamentally distinct from that of the cuprates. In particular, the strong coupling to the magnons advocates active roles of light orbitons in spin dynamics and electron pairing in ironmore » pnictides.« less

Quantum oscillations in the parent magnetic phase of an iron arsenide high temperature superconductor.

Journal Article Sebastian, Suchitra ; Gillett, J ; Harrison, N ; ... - Journal of Physics: Condensed Matter

We report measurements of quantum oscillations in SrFe{sub 2}As{sub 2}--which is an antiferromagnetic parent of the iron arsenide family of superconductors--known to become superconducting under doping and the application of pressure. The magnetic field and temperature dependences of the oscillations between 20 and 55 T in the liquid helium temperature range suggest that the electronic excitations are those of a Fermi liquid. We show that the observed Fermi surface comprising small pockets is consistent with the formation of a spin-density wave. Our measurements thus demonstrate that high T{sub c} superconductivity can occur on doping or pressurizing a conventional metallic spin-densitymore » wave state.« less

Columnar dimer and plaquette resonating-valence-bond orders in the quantum dimer model

Journal Article Leung, P W ; Chiu, K C ; Runge, K J - Physical Review, B: Condensed Matter

We study the nature of the ground state of the quantum dimer model proposed by Rokhsar and Kivelson by diagonalizing the Hamiltonian of the model on square lattices of size {ital L}{times}{ital L}, where {ital L}{le}8, with periodic boundary conditions. Finite-size scaling studies of the columnar order parameter and the low lying excitation spectrum show no evidence of a dimer liquid state in any finite region of the zero temperature phase diagram. In addition, we find evidence of a transition from the columnar dimer state to an intermediate state at a negative value of {ital V}/{ital J}. This state ismore »« less
