Photoinduced magnetic phase transition and remarkable enhancement of magnetization for a photochromic single-molecule magnet

摘要

By increasing contact between pre-existing paramagnetic centers and photoinduced radicals, a photochromic single-molecule magnet with large magnetization change (+20.9%) at room temperature and paramagnetic to ferromagnetic transition was successfully achieved. The increasing amplitude of magnetization was the largest among the radical-based photomagnetic systems.
