  • The arrangement of magnetic ions between layers of NbS2 affects it as though a giant magnetic field is applied in different directions for electrons moving with opposite velocities. This discovery goes beyond the reach of conventional magnets, and opens up the way to custom-made effective fields engineered to guide materials into new territory.

  • Spectroscopic and structural measurements often give conflicting results about the role of disorder in determining the properties of energy materials. A hybrid neutron scattering technique is used to measure atomic correlations in time and space for cubic GeTe, revealing that anisotropic elastic interactions mimic disorder but the time-averaged structure is crystalline.
