"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.

Unveiling Unusual Ultrafast Motion and Rare Physics in Layered Magnetic Materials and Uranium Ditelluride Crystals

Scientists have discovered an unusual ultrafast mechanical motion tied to a change in magnetic state in layered antiferromagnetic materials. By scrambling the ordered orientation of electron spins in the material using ultrafast laser pulses, the researchers observed a sliding motion between layers, with each oscillation occurring at an incredible speed of 10 to 100 picoseconds. This discovery could have important implications for nanodevices requiring ultra-precise and fast motion control, such as high-speed nanomotors for biomedical applications.
