Structural distortions of frustrated quantum spin lattices in high magnetic fields
Structural distortions of frustrated quantum spin lattices in high magnetic fields
We study the stability of some strongly frustrated antiferromagnetic spin lattices in high magnetic fields against lattice distortions. In particular, we consider a spin-s anisotropic Heisenberg antiferromagnet on the square-kagom\'{e} and kagom\'{e} lattices. The independent localized magnons embedded in a ferromagnetic environment, which are the ground state at the saturation …
