First observation of Bose-Einstein condensation of two-magnon bound state in spin-1 triangular lattice reported

Using the Multi-frequency High Field Electron Spin Resonance Spectrometer at the Steady-State High Magnetic Field Facility (SHMFF), researchers observed the first-ever Bose-Einstein condensation (BEC) of a two-magnon bound state in a magnetic material. The facility is in the Hefei Institutes of Physical Science of the Chinese Academy of Sciences and includes a research team from Southern University of Science and Technology, Zhejiang University, Renmin University of China, and the Australian Nuc...
