Every day, new technologies require more precision in the intrinsic properties of the materials used. To meet increasingly specific requirements, physicists are interested in a generation of artificial materials, the properties of which can be controlled. Researchers at the University of Geneva (UNIGE), Switzerland, in collaboration with French and English teams, have succeed in manipulating the properties of two oxides which make up the artificial material, more exactly they managed to modify the magnetic properties which can be either ferromagnetic or antiferromagnetic; that is, with or without net magnetic moment.
The scientists have demonstrated, in their study published in Nature Communications, that they are able now to control the magnetism in this type of materials and that they could, in the near future, offer tailored materials for the devices of tomorrow.
The invention could be used in future devices to transmit wireless data ten times faster.
Graphene acts like polarized sunglasses Their microchip works by protecting sources of wireless data — which are essentially sources of invisible radiation — from unwanted radiation, ensuring that the data remain intact by reducing source corruption. They discovered that graphene can filter out radiation in much the same way as polarized glasses.
The University of Geneva (French: Université de Genève, informally known as Geneva University or UNIGE) is a public research university located in Geneva, Switzerland.
It was founded in 1559 by John Calvin, as a theological seminary and law school. It remained focused on theology until the 17th century, when it became a center for Enlightenment scholarship. In 1873, it dropped its religious affiliations and became officially secular. Today, the university is the second-largest university in Switzerland by number of students. In 2009, the University of Geneva celebrated the 450th anniversary of its founding.
UNIGE has programs in various fields but is particularly acknowledged for its academic and research programs in international relations (with Geneva being hostess to a dense agglomeration of international organizations), law, astrophysics, astronomy, genetics (with a record of prominent contributions to the fields of planetary science, genetics, developmental psychology, neuroscience, and theology). The university holds and actively pursues teaching, research, and community service as its primary objectives.
