Researchers observe quantum critical Bose gas of magnons in quasi-2D antiferromagnet

Three-dimensional (3D) antiferromagnets are materials in which magnetic moments of atoms or ions are arranged in a 3D lattice structure with neighboring spins aligned in opposite directions. Physicists have observed a fascinating magnetic field–induced phase transition in these materials, described at magnon Bose-Einstein condensation (BEC). Three-dimensional (3D) antiferromagnets are materials in which magnetic moments of atoms or ions are arranged in a 3D lattice structure with neighboring spins aligned in opposite directions.
