preserves the spin structure of a Fe3Cr single‐molecule magnet of current interest in molecular spintronics. Magnetic polarization at metal sites is measured over a broad temperature range (from 10 to 300 K) by X‐ray magnetic circular dichroism (XMCD), which provides the required monolayer sensitivity. The data are used to evaluate FeCr superexchange coupling interactions, which compare well with bulk‐phase
舒适的环境:与金表面的相互作用完全保留了分子自旋电子学中当前关注的Fe 3 Cr单分子磁体的自旋结构。X射线磁性圆二色性(XMCD)在较宽的温度范围(10至300 K)中测量金属部位的磁极化,从而提供所需的单层灵敏度。该数据用于评估FeCr超交换耦合相互作用,与体相值在符号和强度上都很好地比较(见图)。
