A research team led by Youtarou Takahashi from the RIKEN Center for Emergent Matter Science has demonstrated a novel phenomenon called magnetochiral dichroism, which prevents light from propagating parallel or antiparallel to the direction of magnetization. The discovery, which was made in the multiferroic 'helimagnet' gallium-doped copper iron oxide, could lead to new possibilities in the control of light at gigahertz and terahertz frequencies.
