New Device To Boost Data Storage Capacity Of Your Phone, PC

Washington: Scientists have developed a new type of holographic memory device that could provide unprecedented data storage capacity and data processing capabilities in electronic devices.

Researchers from the University of California, Riverside, Bourns College of Engineering and Russian Academy of Science developed a prototype of the new memory device that uses spin waves , a collective oscillation of spins in magnetic materials, instead of the optical beams.

Spin waves are advantageous because spin wave devices are compatible with the conventional electronic devices and may operate at a much shorter wavelength than optical devices, allowing for smaller electronic devices that have greater storage capacity, researchers said.

Experimental results obtained by the team show it is feasible to apply holographic techniques developed in optics to magnetic structures to create a magnonic holographic memory device.

"The results open a new field of research, which may have tremendous impact on the development of new logic and memory devices," said Alexander Khitun, the lead researcher, who is a research professor at UC Riverside.

Holography is a technique based on the wave nature of light which allows the use of wave interference between the object beam and the coherent background.
