单链磁体展现出磁性双稳态和缓慢的磁弛豫行为,使其在化学、物理学和材料科学领域备受关注.虽然各种各样的单链磁体已经被设计并合成出来,但是通过光、热和压力外界刺激诱导单链磁体的性能依然是一个科学难题.光子的能量可以匹配不同电子结构间的能垒,调控磁各向异性以及磁耦合作用,进而有效地调控单链磁体的磁性双稳态,所以光诱导单链磁体近年来成为分子材料领域研究的热点课题.本文全面地介绍了现有光诱导单链磁体的种类、结构、磁性质,并对其研究方向进行了展望.
Single-stranded magnets exhibit magnetic bistability and slow magnetic relaxation behavior that make them of interest in the fields of chemistry, physics and materials science.Although a variety of single-stranded magnets have been designed and synthesized, Light, heat and pressure induced by external stimuli single-stranded magnets performance is still a scientific problem.Photon energy can match the energy barrier between different electronic structures, regulating magnetic anisotropy and magnetic coupling, and thus effectively control the single-stranded magnets Therefore, light-induced single-stranded magnets have become hot topics in the field of molecular materials in recent years.In this paper, the types, structures and magnetic properties of light-induced single-stranded magnets are introduced comprehensively, and their research directions are also prospected .
