Magnetic and spin-based technologies for data storage and processing pose unique challenges for information transduction to light because of magnetic metals optical loss, and the inefficiency and resistivity of semiconductor spin-based emitters at room temperature. Transduction between magnetic and optical information in typical organic semiconductors poses additional challenges as the Faraday and Kerr magnetooptical effects rely on the electronic spin-orbit interaction, and the spin-orbit interaction in organics is weak. Other methods of coupling light and spin have emerged in organics, however, as the spin-dependent character of exciton recombination, with spin injection from magnetic electrodes, provides magnetization-sensitive light emission, although such approaches have been limited to low temperature and low polarization efficiency. Here we demonstrate room temperature information transduction between a magnet and an organic light emitting diode that does not require electrical current, based on control via the magnets remanent field of the exciton recombination process in the organic semiconductor.
Interacting Bosons, loaded in artificial lattices, have emerged as a modern platform to explore collective manybody phenomena, quantum phase transitions and exotic phases of matter as well as to enable advanced on chip simulators. Such experiments st
Interacting bosonic particles in artificial lattices have proven to be a powerful tool for the investigation of exotic phases of matter as well as phenomena resulting from non-trivial topology. Exciton-polaritons, bosonic quasi-particles of light and
The magnetoelectroluminescence of conjugated organic polymer films is widely accepted to arise from a polaron pair mechanism, but their magnetoconductance is less well understood. Here we derive a new relationship between the experimentally measurabl
We report measurement of the ensemble averaged transverse spin relaxation time (T2*) in bulk and few molecules of the organic semiconductor tris(8-hydroxyquinolinolato aluminum) or Alq3. This system exhibits two characteristic T2* times, the longer o
The effect of hyperfine interaction on the room-temperature defect-enabled spin filtering effect in GaNAs alloys is investigated both experimentally and theoretically through a master equation approach based on the hyperfine and Zeeman interaction be
