Researchers from IMDEA-Nanociencia Institute and from Autonoma and Complutense Universities of Madrid (Spain) have managed to give graphene magnetic properties.
The breakthrough, published in the journal Nature Physics, opens the door to the development of graphene-based spintronic devices, that is, devices based on the spin or rotation of the electron, and could transform the electronics industry.
Scientists were already aware that graphene, an incredible material formed of a mesh of hexagonal carbon atoms, has extraordinary conductivity, mechanical and optical properties. Now it is possible to give it yet one more property: magnetism, implying a breakthrough in electronics.
This is revealed in the study that the Madrid Institute for Advanced Studies in Nanoscience (IMDEA-Nanociencia) and Autonoma Autonomous (UAM) and Complutense (UCM) universities of Madrid have just published in the ‘Nature Physics’ journal. Researchers have managed to create a hybrid surface from this material that behaves as a magnet.
“In spite of the huge efforts to date of scientists all over the world, it has not been possible to add the magnetic properties required to develop graphene-based spintronics. However these results pave the way to this possibility,” highlights Prof. Rodolfo Miranda, Director of IMDEA-Nanociencia.
Spintronics is based on the charge of the electron, as in traditional electronics, but also on its spin, which determines its magnetic moment. A material is magnetic when most of its electrons have the same spin.
As the spin can have two values, its use adds two more states to traditional electronics. Thus, both data processing speed and quantity of data to be stored on electronic devices can be increased, with applications in fields such as telecommunications, computing, energy and biomedicine.
In order to develop a graphene-based spintronic device, the challenge was to ‘magnetize’ the material, and researchers from Madrid have found the way through the quantum and nanoscience world.
