Researchers reveal the operation of the magnets

What they got scientists from the University of Colorado and National Institute of Standards and Technology could lead to the construction of faster computers and intelligent. Researchers have revealed the inner life of the magnets using the light source the world's fastest, able to create X-ray pulsations cuantrillonésima just one second in duration. A technology under the name of High Harmonic Generation.

As a result the team could see how it works magnetism in nickel and iron atom, they realized that every metal behaves differently. Consider a second cuantrillonésima is a million times faster than a millionth of a second.

And which according to experts, the next generation of computers' hard disks use a magnetic optical system to achieve high capacity units.

From what researchers strive to make progress achieved in many of the questions that remain unanswered. One will focus on how the delivery of optical energy in the magnetic system can be optimized for performance unit.

According to Tom Smith, research scientist:

The discovery that iron and nickel are fundamentally different in their interaction with light ultrafast time scales, suggesting that the alloy magnetic hard drives may be designed to improve the delivery of optical energy in the system of spins.

Silva speaks of magnetism, which exists because the "turns" of a magnet are aligned at a point in the same direction. According to Silva:

What we have seen for the first time is that the twists and turns iron into nickel react to light in different ways, with the iron mixed by turning the light so much easier than in nickel. This difference was only possible through the use of technology extremely fast X-ray that we develop.

A technology with High Harmonic Generation nickname can cover a large portion of the electromagnetic spectrum, in this case, able to include the spectral region where nickel and iron interact strongly with x-rays
