Multiferroicity in the generic easy-plane triangular lattice antiferromagnet RbFe(MoO4)(2)

RbFe(MoO4)(2) is a quasi-two-dimensional (quasi-2D) triangular lattice antiferromagnet (TLA) that displays a zero-field magnetically driven multiferroic phase with a chiral spin structure. By inelastic neutron scattering, we determine quantitatively the sp ...

Unconventional Fermi Surface Instabilities in the Kagome Hubbard Model

Ronny Thomale

We investigate the competing Fermi surface instabilities in the kagome tight-binding model. Specifically, we consider on-site and short-range Hubbard interactions in the vicinity of van Hove filling of the dispersive kagome bands where the fermiology promo ...

Correlation between spin structure oscillations and domain wall velocities

André Bisig

Magnetic sensing and logic devices based on the motion of magnetic domain walls rely on the precise and deterministic control of the position and the velocity of individual magnetic domain walls in curved nanowires. Varying domain wall velocities have been ...

Three-Dimensional Spin Rotations at the Fermi Surface of a Strongly Spin-Orbit Coupled Surface System

Jan Hugo Dil

The spin texture of the metallic two-dimensional electron system (root 3 x root 3)-Au/Ge(111) is revealed by fully three-dimensional spin-resolved photoemission, as well as by density functional calculations. The large hexagonal Fermi surface, generated by ...

Dissociation dynamics of singly charged vortices into half-quantum vortex pairs

Benoît Marie Joseph Deveaud, Vincenzo Savona, Timothy Chi Hin Liew, Konstantinos Lagoudakis, Francesco Manni

The quest for identification and understanding of fractional vorticity is a major subject of research in the quantum fluids domain, ranging from superconductors, superfluid Helium-3 to cold atoms. In a two-dimensional Bose degenerate gas with a spin degree ...

Spin-wave analysis of the transverse-field Ising model on the checkerboard lattice

Frédéric Mila

The ground-state properties of the S = 1/2 transverse-field Ising model on the checkerboard lattice are studied using linear spin-wave theory. We consider the general case of different couplings between nearest neighbors (J(1)) and next-to-nearest neighbor ...

Experimental investigation of the low-temperature features of a random Heisenberg spin chain

Joël Mesot, Krunoslav Prsa

Low-dimensional spin systems, consisting of arrays of spins arranged in chains or ladders, have been investigated intensively in recent years using both exactly solvable theoretical models as well as a variety of experimental techniques. In case of random ...

Degeneracy and ordering of the noncoplanar phase of the classical bilinear-biquadratic Heisenberg model on the triangular lattice

Frédéric Mila, Karlo Penc

We investigate the zero-temperature behavior of the classical Heisenberg model on the triangular lattice in which the competition between exchange interactions of different orders favors a relative angle between neighboring spins Phi is an element of (0,2 ...

Kagome Antiferromagnet: A Chiral Topological Spin Liquid?

Inspired by the recent discovery of a new instability towards a chiral phase of the classical Heisenberg model on the kagome lattice, we propose a specific chiral spin liquid that reconciles different, well-established results concerning both the classical ...
