Interactions between electrons underpin some of the most interesting – and useful -- effects in materials science and condensed-matter physics. This work demonstrates that, in the new family of so-called "monolayer semiconductors" that are only one atomic layer thick, electron-electron interactions can lead to the sudden and spontaneous formation of a magnetized state, analogous to the appearance of magnetism in conventional materials like iron.
This work reports the first observation of the dynamical generation of a spin polarized current from an antiferromagnetic material into an adjacent non-magnetic material and its subsequent conversion into electrical signals
Electron spin resonance work shows how transition metal can retain quantum information, important work on the path to next-generation quantum technologies.
In a uranium-based compound once dismissed as boring, scientists watched superconductivity arise, perish, then return to life under the influence of high magnetic fields.
Scientists used high magnetic fields and low temperatures to study crystals of URu2–xFexSi2. Using these conditions, they explored an intriguing state of matter called the "hidden order phase" that exhibits emergent behavior. Emergent behavior occurs when the whole is greater than the sum of its parts, meaning the whole has exciting properties that its parts do not possess; it is an important concept in philosophy, the brain and theories of life. This data provide strict constraints on theories of emergent behavior.
In the 14 years since its discovery, graphene has amazed scientists around the world with both the ground-breaking physics and technological potential it displays. Recently, scientists from Penn State University added to graphene's gallery of impressive scientific achievements and constructed a map that will aid future exploration of this material. This work is emblematic of the large number of university-based materials research efforts that use the MagLab to explore the frontiers of science.
Analogous to the unique spectral fingerprint of any atom or molecule, researchers have measured the spectrum of optical excitations in monolayer tungsten diselenide (WSe2), which is a member of a new family of ultrathin semiconductors that are just one atomic layer thick.
A lot of the research conducted in powerful magnets ends up having a powerful effect on our day-to-day lives.
This approach to building “qubits” could be a promising tool for developing quantum computers.
Scientists begin to fill in the blanks on transition metal dichalcogenides.
