Lossless electric current at room temperature

Ferromagnetic properties allow electric current to flow over the surface of special films, but normally only under very low temperatures. Something of great importance is that this electric current is generated spontaneously and without any kind of external magnetic field – electric current without magnetism.

Using Cr as an atomic sized magnet and Sb and Te to help “glue” their alignment into place, apparently allows this electric current to be not only lossless but at room temperature.

This breakthrough could have major implications for the development of new electronic devices. Lossless electric current means that there would be no energy lost as heat, which would make these devices much more efficient. Additionally, the ability to generate electric current at room temperature would make these devices much more practical.

The research was conducted by a team of scientists from the University of California, Berkeley. They published their findings in the journal Nature Physics.

The team created a thin film of Cr, Sb, and Te. The Cr atoms were arranged in a ferromagnetic pattern, meaning that they all had the same magnetic orientation. The Sb and Te atoms were then arranged around the Cr atoms, helping to keep their alignment in place.

When the researchers applied an electric field to the film, they found that an electric current flowed over the surface. The current was generated spontaneously, without any need for an external magnetic field.

The current was also lossless, meaning that no energy was lost as heat. This is because the electrons were able to move freely through the film without encountering any resistance.

The researchers were able to repeat the experiment at room temperature, which is a major breakthrough. This means that the technology could be used to create new electronic devices that are efficient and practical.

The team is continuing to study the properties of the film. They are also working to develop new ways to create and control the electric current.

If the research is successful, it could lead to the development of new types of transistors, solar cells, and other electronic devices. These devices could be used in a wide range of applications, including energy efficiency, telecommunications, and medical imaging.

The implications of this research are significant. Lossless electric current could lead to the development of new and more efficient electronic devices. These devices could be used to improve energy efficiency, telecommunications, and medical imaging.

The research is still in its early stages, but it has the potential to revolutionize the way we use electricity.
