There Are Only Two Words To Sum Up These Findings

RIKEN physicists have discovered how interactions between electrons can stabilize a repeating arrangement of swirling magnetic patterns known as skyrmions, which could help to further exploit these structures.

The spin of an electron causes it to behave like a miniature magnet. In a skyrmion, many of these spins are arranged in a swirling pattern that resembles a tiny tornado. Skyrmions are highly promising as a means of carrying information in a new generation of high-density, low-energy data-storage devices.

Skyrmions behave as if they are distinct particles, and multiple skyrmions can arrange themselves into a regular grid within certain types of material. But researchers are still debating how these stable skyrmion lattices form.

Those words are:

“Wait: What?”

  1. All I know is, Ajax All Purpose Cleaner with Ammonia, introduced in 1962, was the first major competitor to Procter and Gamble’s Mr. Clean (debuted 1958). Ajax’s success as the so called “White Tornado” forced Procter and Gamble to introduce its own ammoniated cleaner, Top Job, in 1963.

    Our family wasn’t aware of these brand wars, since at any given time we’d have all three (or four, if you include powdered Ajax without ammonia) in our cabinet, depending only on what was on sale.
