Concept of the helimagnet-based memory devices. The directions of the atomic magnetic moments, depicted by the colored allows, are arranged into a spiral. Chirality, the right- and left-handed ...

Researchers have mapped magnetic fields in three dimensions, a major step toward solving what they call the 'grand challenge' of revealing 3D magnetic configuration in magnetic materials. The work has ...

Forward-looking: Magnetic storage technology in hard disks has undergone significant evolution in recent years. Following Perpendicular Magnetic Recording (PMR), Shingled Magnetic Recording (SMR), and ...

Relatively inexpensive secondary disk storage is gaining a significant foothold in corporate data centers, according to a survey of more than 1,000 IT managers that’s due to be released next month.

The first storage media — paper tape and punched cards — were inefficient, slow and bulky. These gave way to magnetic storage: core memory, drums and, finally, hard drives. For backup, there were ...

Quantum mechanics states that electrons have two stable spins—up and down. With the advent of nanoscale fabrication methods, device companies are harnessing this knowledge to create devices. The ...

A team of researchers has proposed a new concept for magnet-based memory devices, which might revolutionize information storage devices owing to their potential for large-scale integration, ...
