| Outline of Final Research Achievements |
A difference in refractive index with the reversal of the propagation vector of light, termed directional birefringence, is observed in some multiferroics. It was predicted that this phenomenon may act on a photon as the Lorentz force on an electron. An experimental study is performed on multiferroic copper metaborate to confirm the presence of the Lorentz force on a photon.
In order to enlarge the Lorentz force, the directional dichroism/birefringence must be enhanced. It has been discovered that the application of a high magnetic field on copper metaborate enhances the directional dichroism and results in the one-way transparency.
