Anharmonic magnon excitations in noncollinear and charge-ordered RbFeFeF
M. Songvilay, E. E. Rodriguez, R. Lindsay +4
RbFeFeF is an example of a charge ordered antiferromagnet where iron sites, with differing valences, are structurally separated into two interpenetrating sublatti…
Orphan spins and bound in-gap states in the antiferromagnet CaFeO
C. Stock, E. E. Rodriguez, N. Lee +11
CaFeO is an anisotropic antiferromagnet with two competing () and ($\uparrow \downarrow \uparrow \downar…
Competing spin density wave, collinear, and helical magnetism in Fe1+xTe
C. Stock, E. E. Rodriguez, P. Bourges +5
The Fe1+xTe phase diagram consists of two distinct magnetic structures with collinear order present at low interstitial iron concentrations and a helical phase at large values of x…
Solitary magnons in the antiferromagnet CaFeO
C. Stock, E. E. Rodriguez, N. Lee +10
CaFeO is a anisotropic antiferromagnet based upon zig-zag chains having two competing magnetic structures, denoted as the A ($\uparrow \uparrow \downarro…
Soft striped magnetic fluctuations competing with superconductivity in Fe_{1+x}Te
C. Stock, E. E. Rodriguez, O. Sobolev +5
Neutron spectroscopy is used to investigate the magnetic fluctuations in Fe_{1+x}Te - a parent compound of chalcogenide superconductors. Incommensurate "stripe-like" excitations so…
The magnetic and structural properties near the Lifshitz point in Fe1+xTe
E. E. Rodriguez, D. A. Sokolov, C. Stock +5
We construct a phase diagram of the parent compound Fe1+xTe as a function of interstitial iron x in terms of the electronic, structural, and magnetic properties. For a concentratio…
