我们实验证明了单向透明的光在多铁性CuB2O4。该材料对于沿一个方向传播的光是透明的，而对于沿相反方向传播的光是不透明的。这种新的透明性是电偶极和磁偶极跃迁相消干涉的结果。该效应的实现是通过施加高磁场和适当选择光的传播方向来实现的，这与我们的非互易定向二向色性的量子力学公式相一致。
We experimentally demonstrate one-way transparency of light in multiferroic CuB2O4. The material is rendered transparent for light propagating in one direction, while opaque for light propagating in the opposite direction. The novel transparency results from a destructive interference of the electric dipole and magnetic dipole transitions. The realization of the effect has been accomplished by the application of a high magnetic field and the proper selection of the propagation direction of light in agreement with our quantum mechanical formulation of nonreciprocal directional dichroism.
