Spin nematic states in spin-1 antiferromagnets with easy-axis anisotropy
Alexey Sizanov, Arseny Syromyatnikov
It is well known that spin nematic phases can appear in either frustrated magnets or in those described by Hamiltonians with large exotic non-Heisenberg terms like biquadratic exch…
Spin nematic states in antiferromagnets containing ferromagnetic bonds
Alexey Sizanov, Arseny Syromyatnikov
The majority of recent works devoted to spin nematic phases deal with either frustrated magnets or with those described by Hamiltonians with large non-Heisenberg terms. We show in…
Collective excitations in two-dimensional antiferromagnet in strong magnetic field
A. V. Syromyatnikov
We discuss spin- two-dimensional (2D) Heisenberg antiferromagnet (AF) on a square lattice at T=0 in strong magnetic field H near its saturation value . A perturbation…
Spin-wave interaction in two-dimensional ferromagnets with dipolar forces
A. V. Syromyatnikov
We discuss the spin-wave interaction in two-dimensional (2D) Heisenberg ferromagnet (FM) with dipolar forces at using 1/S expansion. A comprehensive analysis is carr…
Nonfrustrated magnetoelectric with incommensurate magnetic order in magnetic field
A. V. Syromyatnikov
We discuss a model nonfrustrated magnetoelectric in which strong enough magnetoelectric coupling produces incommensurate magnetic order leading to ferroelectricity. Properties of t…
Frustrated impurity spins in ordered two-dimensional quantum antiferromagnets
A. V. Syromyatnikov, S. V. Maleyev
Dynamical properties of an impurity spin coupled symmetrically to sublattices of ordered 2D Heisenberg quantum antiferromagnet (i.e., frustrated impurity spin) are discussed at $T\…
