A new wave of high -speed magnetic control

Researchers at the Max Planck Institute of the MPSD structure and dynamics have developed an innovative way to study the super magnetic in the material. They have shown the generation and application of magnetic field steps, as a magnetic field is operated on the issue of Pico again.

It was action Published in Light nature.

Magnetic fields are essential to control the material magnet. Under fixed or varying circumstances slowly, the substance magnet is compatible with the outer field, such as the compass needle. However, the dynamics of the new magneticity appear completely when magnetic fields change on high -speed time domains – from the time of the substance response.

This fast transit is of great importance for the basic research in cases of unbalanced material and possible applications in the magnetic memory of the next generation, where the writing speeds are faster, it is very important.

To deal with this challenge, the research team designed a new, super-connecting device capable of producing superconductomical magnetic field steps-crowded magnetic changes with the climbing of the bikoskend range and nanoparticles.

“Our goal is to create a high -speed global incentive that can switch any magnetic sample between stable magnetic cases,” says lead author Giovanni de Vici. “This penetration can push progress in both science and technology.”

Harmony of high -speed magnetic steps

The team, led by Andrea Cavalleri, has achieved this feat by extinguishing superior strokes in the gentle yba₂cu₃o tablet exhibition of an external magnetic field. The superior currents are naturally formed to expel magnetic fields of super -conductivity.

“By suddenly disrupting these currents using super laser pulses, we can generate high-speed magnetic field steps with approximately ups in the climbing of one of the Picoskont-one trillion second trillion,” says co-colleague Gregor Gotzo.

“The development of a way to track these magnetic crossings in the actual time was a great challenge,” Michel Bodes, the co -author, explains. The researchers put a spectator of a spectator near the highly delivery sample to achieve this. The visual properties of crystal change in response to the local magnetic field.

This effect allows the team to track the development of the magnetic field by analyzing the polarization of the pulse of the laser pulse.

“With this approach, we have achieved the accuracy of PicoseCond without an unprecedented sensitivity,” co -author Sebastian Fava.

Although current magnetic steps are not achieved after replacing the full magnet, researchers believe that improving the device engineering can enhance the capacity and speed of the magnetic field.

“With appropriate improvements, we imagine applications ranging from controlling the transmission of the phase to completing the switching of magnetic arrangement parameters,” says Cavalleri.
