Magnons and Excitation Continuum in XXZ triangular antiferromagnetic model: Application to $B a_{3} C o S b_{2} O_{9}$

E. A. Ghioldi, A. Mezio, L. O. Manuel +3

We investigate the excitation spectrum of the triangular-lattice antiferromagnetic $X X Z$ model using series expansions and mean field Schwinger bosons approaches. The single-magnon…

Magnetic Excitations in the Spin-Spiral State of TbMnO $_{3}$ and DyMnO $_{3}$

Alexander I. Milstein, Oleg P. Sushkov

We calculate spectra of magnetic excitations in the spin-spiral state of perovskite manganates. The spectra consist of several branches corresponding to different polarizations and…

Ruthenium-Europium configuration in the Eu2Ru2O7 pyrochlore

S. Muñoz Pérez, R. Cobas, J. M. Cadogan +3

The magnetic and electronic properties of Eu2Ru2O7 are discussed in terms of the local ruthenium and europium coordinations, electronic band structure calculations and molecular or…

Competing exchange interactions on the verge of a metal-insulator transition in the two-dimensional spiral magnet Sr $_{3}$ Fe $_{2}$ O $_{7}$

J. -H. Kim, Anil Jain, M. Reehuis +12

We report a neutron scattering study of the magnetic order and dynamics of the bilayer perovskite Sr $_{3}$ Fe $_{2}$ O $_{7}$ , which exhibits a temperature-driven metal-insulator transition…

Local Kondo temperatures in atomic chains

Ricardo Agundez, Joe Salfi, Sven Rogge +1

We study the effect of disorder in strongly interacting small atomic chains. Using the Kotliar- Ruckenstein slave-boson approach we diagonalize the Hamiltonian via scattering matri…

Element-Specific Depth Profile of Magnetism and Stoichiometry at the La0.67Sr0.33MnO3/BiFeO3 Interface

J. Bertinshaw, S. Brück, D. Lott +14

Depth-sensitive magnetic, structural and chemical characterization is important in the understanding and optimization of novel physical phenomena emerging at interfaces of transiti…

Spontaneous breaking of time reversal symmetry in strongly interacting two dimensional electron layers in silicon and germanium

S. Shamim, S. Mahapatra, G. Scappucci +3

We report experimental evidence of a remarkable spontaneous time reversal symmetry breaking in two dimensional electron systems formed by atomically confined doping of phosphorus (…

Phase diagram of the frustrated quantum-XY model on the honeycomb lattice studied by series expansions: Evidence for proximity to a bicritical point

Jaan Oitmaa, Rajiv R. P. Singh

We study the nearest-neighbor exchange ( $J_{1}$ ) and second-neighbor exchange ( $J_{2}$ ) XY antiferromagnet on the honeycomb lattice using ground state series expansions around N{é}el,…
