How to induce magnetism in graphene

Graphene, a two-dimensional structure made of carbon, is a material with excellent mechanical, electronic and optical properties. However, it did not seem suitable for magnetic applications. Together with international partners, Empa researchers have now succeeded in synthesizing a unique nanographene predicted in the 1970s, which conclusively demonstrates that carbon in very specific forms has magnetic … Read more How to induce magnetism in graphene

FEFU and FEB RAS scientists are close to Integrate Silicon Electronics and Spintronics

Scientists from Far Eastern Federal University (FEFU) and the Far Eastern Branch of the Russian Academy of Sciences (FEB RAS) developed the nanoheterostructure consisted of a nanocrystal magnetite film (Fe3O4) covering a silicon substrate with an additional layer of silicon oxide (SiO2/Si). Its magnetic and magnetotransport properties may help to design highly efficient hybrid semiconductor … Read more FEFU and FEB RAS scientists are close to Integrate Silicon Electronics and Spintronics

Paramagnetic spins take electrons for a ride, produce electricity from heat

An international team of researchers has observed that local thermal perturbations of spins in a solid can convert heat to energy even in a paramagnetic material – where spins weren’t thought to correlate long enough to do so. This effect, which the researchers call “paramagnon drag thermopower,” converts a temperature difference into an electrical voltage. … Read more Paramagnetic spins take electrons for a ride, produce electricity from heat

Spin devices get a paint job

Physicists created a new way to fabricate special kinds of electronic components known as spintronic devices. These high-performance, low-power devices have a promising future, so efficient ways to make them are highly sought after. The new fabrication method is interesting because it uses organic molecules which are relatively easy to configure for different purposes. Layers … Read more Spin devices get a paint job

Spintronics: Physicists discover new material for highly efficient data processing

A new material could aid in the development of extremely energy efficient IT applications. The material was discovered by an international research team in cooperation with Martin Luther University Halle-Wittenberg (MLU). The electrons at the oxide interface of the material possess special properties which drastically increase the conversion rate of spin current to charge current. … Read more Spintronics: Physicists discover new material for highly efficient data processing
