ARCS maps collaborative magnetic spin behavior in iron telluride
— Researchers have long thought that magnetism and superconductivity are mutually exclusive. The former typically involves localized atomic electrons. The latter requires freely propagating, itinerant electrons.

Unexpected Magnetic Excitations in Doped Insulator Surprise Researchers
— When doping a disordered magnetic insulator material with atoms of a nonmagnetic material, the conventional wisdom is that the magnetic interactions between the magnetic ions in the material will be weakened.

Neutron Analysis Reveals Unique Atomic-Scale Behavior of "Cobalt Blue"
— Neutron scattering studies of "cobalt blue," a compound prized by artists for its lustrous blue hue, are revealing unique magnetic characteristics that could answer questions about mysterious properties in other materials.

SEQUOIA Measures Magnetic Excitations Revealing Exotic Physics in One Dimension
— Neutron scattering is a powerful tool for studying the strength of the magnetic interactions between a material’s magnetic ions.

Neutrons Show LiF Tunnel Barriers in Spin Valve Devices Improve Efficiency
— Researchers are working to discover new materials for spin valves, devices used in magnetic sensors, random access memories, and hard disk drives. Spin valves work by means of two or more conducting magnetic materials that alternate their electrical resistance depending on the alignment of the layers.
