Spiraling beams differentiate antiferromagnetic states

Apr 29, 2023 (Nanowerk News) Using spiraling x-ray beams generated at the Advanced Light Source (ALS), researchers differentiated between energetically equivalent (“degenerate”) states in an antiferromagnetic lattice (Physical Review B, "Antiferromagnetic real-space configuration probed by dichroism in scattered x-ray beams with orbital angular momentum"). The work shows the potential of...

More power from waste heat

Apr 29, 2023 (Nanowerk News) When fossil fuels, but also biofuels, are burned, large amounts of the energy are lost as waste heat. Thermoelectric materials could convert this heat into electricity, but they are not yet efficient enough for technical application. A team from the Max Planck Institut für Eisenforschung...
