A simple state-of-the-art spectrometer for student labs: Cost-efficient, instructive, and widely applicable
We present a simple, cost-effective, yet instructive spectrometer for use in undergraduate instructional laboratory courses. Deliberate design choices are made to enhance the learning experience provided by the setup, where every component is accessible to students, allowing them to fully understand the function of each individual item.
New Kind of Magnetism Spotted in an Engineered Material
In an atomically thin stack of semiconductors, a mechanism unseen in any natural substance causes electrons’ spins to align.
New type of magnetism appears in a layered semiconductor
The magnetic properties of materials usually originate from exchange interactions between their electrons, but researchers at ETH Zurich in Switzerland have now discovered a new type of magnetism that disobeys this rule. Known as kinetic magnetism, and previously only predicted theoretically, the new mechanism occurs in a regime where the strength of electron exchange interactions vanishes.
