"suppressing slow processes boosts spin-based data processing to femtosecond speeds... magnetic fields control spin angular momentum/ dynamic spin control in vdW ferromagnet Fe₃GeTe₂... 7-tesla magnetic field accelerates demagnetization process by 60%, simultaneously suppressing demagnetization efficiency by 34%... mechanism based on spin entropy variation within 3-temperature model... high-speed magnetic storage and logic devices operating at or near room temperature where effect was more pronounced"
