Abstract
An organic insulating crystal reversibly becomes a magnetic conductor under UV irradiation. The rapid and qualitative change in the physical properties is wavelength selective and explained by charge transfer between donor and photochemically active acceptor molecules. The photochemical redox reaction in the crystal produces a partially filled band and localized spins simultaneously.
摘要
一种有机绝缘晶体在紫外光照射下可可逆地变为磁性导体。物理性质的快速和定性变化是波长选择性的，并可以通过供体和光化学活性受体分子之间的电荷转移来解释。晶体中的光致氧化还原反应同时产生部分填充的能带和局域自旋。
