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

Magnetic induction is used in technology to convert an applied magnetic field into an electric current and vice versa. Nature also makes extensive use of this principle at the atomic and molecular level giving scientists a window to observe material properties. Using the 25 T Split-Helix magnet, researchers observed changes in the optical properties of organic materials due to currents induced by applied magnetic fields flowing in molecular rings, evidence that could increase the list of materials that could be used in future magnetic technologies.

Move aside, electrons; it's time to make way for the trion.

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.

Scientists discovered how to tune the optical properties of atomically-thin semiconductors, which will aid the design of future microscopic light sensors.

With a sufficiently high magnetic field, scientists can manipulate certain phase transitions in some molecules, a discovery that hints at future technological applications.

A scientist combines high magnetic fields with ultra short laser pulses to probe the mysteries of photosynthesis.

Scientists begin to fill in the blanks on transition metal dichalcogenides.

Utilizing the sensitivity of the NHMFL optics facility, a team of scientists from Georgia Tech, Sandia National Laboratories, Institut Néel, Université Paris-Sud and the NHMFL were able to observe collective oscillations of Dirac Fermions in graphene nanoribbons. The observed effect is tunable by varying the width of the graphene nanoribbons and the applied magnetic field. This observation raises the possibility of graphene based tunable THz devices.
