论文摘要
$^{195} $ PT-NMR测量值的平均直径为4.0 nm的PT纳米颗粒的高磁场在大约$μ_0H = 23.3 $ t的高磁场中进行了研究，以研究纳米粒子的低温电子状态。特征温度$ t^*$，在此下面的核自旋晶格松弛率$ 1/t_1 $偏离散装的松弛率，显示出磁场的依赖性。这种依赖性支持离散能级出现的理论预测。
$^{195}$Pt-NMR measurements of Pt nanoparticles with a mean diameter of 4.0 nm were performed in a high magnetic field of approximately $μ_0 H = 23.3$ T to investigate the low-temperature electronic state of the nanoparticles. The characteristic temperature $T^*$, below which the nuclear spin-lattice relaxation rate $1/T_1$ deviates from the relaxation rate of the bulk, shows a magnetic-field dependence. This dependence supports the theoretical prediction of the appearance of discrete energy levels.
