Abstract
- Abstract: We review the main properties of spin waves condensation to a coherent quantum state, named homogeneously precessing domain (HPD). We describe the long range coherent transport of magnetization by spin supercurrent in antiferromagnetic superfluid . This quantum phenomenon was discovered 20 years ago. Since then, many magnetic extensions of superconductivity and superfluidity have been observed: spin Josephson phenomena, spin-current vortices, spin phase slippage, long distance magnetization transport by spin supercurrents, etc. Several new supercurrent phenomena have been discovered, like magnetically excited coherent quantum states, NMR in the molecular Landau field, spin-current turbulence, formation of stable non-topological solitons, etc. [Copyright &y& Elsevier]
