Magnetic nano-droplet discovery presents telecom opportunity
Researchers in Sweden have successfully created a magnetic soliton – a spin torque generated nano-droplet that could lead to technological innovation in such areas as mobile telecommunications.
First theorised 35 years ago, the magnetic nano-droplet was created in a modified spintronic oscillator by a team from KTH Royal Institute of Technology in Stockholm and the University of Gothenburg.
The droplets take up a space of about 50 to 100nm on a piece of magnetic film.
At their centre, magnetisation points towards the opposite direction, both against the surrounding spin (a quantum physical property) and the applied magnetic field.
"This will open up completely new possibilities in nano-magnetism and spintronics," said Majid Mohseni, a researcher at KTH. "Magnetic nano-droplets have great potential to translate into different applications."
