Ferromagnets are materials that become magnetized and remain so while they are exposed to an external magnetic field. In these materials, electric currents typically induce a so-called transverse Hall voltage (i.e., a voltage ...
A new study has shown for the first time how electrical creation and control of magnetic vortices in an antiferromagnet can be achieved, a discovery that will increase the data storage capacity and speed of next generation ...

When light strongly interacts with matter, it can produce unique quasi-particles called polaritons, which are half light and half matter. In recent decades, physicists explored the realization of polaritons in optical cavities ...
Transporting energy is costly. When a current runs through conductive materials, some of the energy is lost due to resistance as particles within the material interact—just notice the warmth from your phone or laptop. This ...
