Ultrafast Phenomenon Prompts Data Storage Efficiency Hypothesis
DAVIS, Calif., Jan. 30, 2024 — A recent discovery from the University of California, Davis, could enable faster and more efficient magnetic hard drives by using ultrafast laser pulses to process data. The findings could significantly reduce energy consumption for data centers. The current hard drives used in data centers, while much cheaper than the solid-state drives used by many commercial devices, are slow and consume a lot of energy because they use a magnetic field to conduct heat through a wire coil each time an
'Quantum Cocktail' Provides Insight Into Magnetic Storage
ZÜRICH, Jan. 29, 2018 — To speed up the writing and readout of magnetic information from storage devices, researchers are exploring the use of ultrashort laser pulses that can switch magnetic domains in solid-state materials. Although this route shows promise, the large...
Laser Reveals Surprising Optical Effect on Ferromagnets
HAMBURG, Germany, Oct. 5, 2012 — Investigations of magnetism using a free-electron laser unveiled a new mechanism that causes ferromagnetic materials to demagnetize. The finding — previously theorized, but never before observed &dmash; could play a role in reducing the size of...
