"Groundbreaking Study Reveals Magnetic Phenomenon Amplified in Polar Antiferromagnet"

Researchers at Nanjing University and the Chinese Academy of Sciences have discovered giant phonon magnetic moments enhanced by spin fluctuations in Fe2Mo3O8, a polar antiferromagnet. By using magneto-Raman spectroscopy and inelastic neutron scattering, they uncovered the phononic nature of low-lying excitations in Fe2Mo3O8 and detected a sixfold enhancement of the phonon magnetic moment. This finding could lead to new insights into the interplay between magnetism and phonons and pave the way for potential applications in phononic control of magnetic dynamics and spin information devices.
