Abstract

Theoretical investigation with Monte Carlo simulations predicts that thermal spin-switching hysteresis of transition-metal complexes appears even in nanoparticles, but the hysteresis width does not depend only on the interaction strength between molecules but also strongly on the shape and size of the particles.

摘要

蒙特卡罗模拟的理论研究预测，即使在纳米颗粒中，过渡金属配合物的热自旋开关滞后现象也会出现，但滞后宽度不仅取决于分子间的相互作用强度，还强烈依赖于颗粒的形状和大小。
