Description of Capabilities

In many magnetic systems, quantum effects can dominate at low temperatures. We study magnetically insulating systems, including inorganic oxides and organo-metallics using thermal properties and electron spin resonance in pulsed magnetic fields up to 85 T down to 500 mK, and dc fields up to 20 T down to 50 mK. Fascinating phenomena can arise such as Bose-Einstein Condensation, superconductivity, and reduced dimensionality, which we chart in close collaboration with T-4 division.

Description of Capabilities

Ultra-fast pulsed magnetic fields at the National High Magnetic Field Laboratory allow very sensitive measurements of the magnetic field-induced electric polarization, down to fractions of a pC/cm2. In addition, dielectric constant measurements can be performed in DC fields up to 20 T and pulsed fields up to 85 T, and electron spin resonance can be used to probe the magnetic response of a system to an electric oscillating cavity mode. We study organo-metallic and oxide materials for magneto-electric or multiferroic behavior.
