刺激响应材料中电子和磁性的受控调制为磁电或多铁性器件的设计提供了有价值的见解。本文研究了具有顺磁性的半导体金属−有机骨架(MOF)Cu3(C6O6)2对NH_3、H_2S、NO等气体小分子的电磁性质的调制作用。这项研究合并了化学电阻和磁性测试，以揭示MOF经历了电导和磁化的同时变化，这两种变化是由每种气体唯一调制的。响应的特征，包括方向、大小和动力学，受气体分子的物理化学性质的影响。这项研究推进了多功能材料的设计，这些材料能够在化学刺激下同时改变电和磁性能。
Controlled modulation of electronic and magnetic properties in stimuli‐responsive materials provides valuable insights for the design of magnetoelectric or multiferroic devices. This paper demonstrates the modulation of electrical and magnetic properties of a semiconductive, paramagnetic metal−organic framework (MOF) Cu3(C6O6)2with small gaseous molecules, NH3, H2S, and NO. This study merges chemiresistive and magnetic tests to reveal that the MOF undergoes simultaneous changes in electrical conductance and magnetization that are uniquely modulated by each gas. The features of response, including direction, magnitude, and kinetics, are modulated by the physicochemical properties of the gaseous molecules. This study advances the design of multifunctional materials capable of undergoing simultaneous changes in electrical and magnetic properties in response to chemical stimuli.
