Berezinskii-Kosterlitz-Thouless region and magnetization plateaus in easy-axis triangular weak-dimer antiferromagnet KCo(SeO)
Ying Fu, Han Ge, Jian Chen +11
We investigate the magnetic phase diagram of the bilayer triangular antiferromagnet KCo(SeO), revealing a rich interplay among geometric frustration, bilayer coupli…

Bose-Einstein condensation of a two-magnon bound state in a spin-one triangular lattice
Jieming Sheng, Jia-Wei Mei, Le Wang +31
In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired in…
