Magnetic ‘hedgehogs’ could Store Big Data in a Small Space

Magnetic patterns that are similar to a hedgehog’s spikes could lead to more efficient — and larger-scale — data storage, a new study has found.

New study reveals a zoo of magnetic patterns at the atomic scale. Atomic-scale magnetic patterns resembling a hedgehog’s spikes could result in hard disks with massively larger capacities than today’s devices, a new study suggests. The finding could help data centers keep up with the exponentially increasing demand for video and cloud data storage.

In a study published today in the journal Science, researchers at The Ohio State University used a magnetic microscope to visualize the patterns, formed in thin films of an unusual magnetic material, manganese germanide...
