Data and analysis code supporting the PhD thesis 'Coherent dynamics of atomic spins on a surface'

This data set contains the raw data files as well as the analysis code used to produce all the experimental plots in the PhD thesis 'Coherent dynamics of atomic spins on a surface' by Lukas M. Veldman under supervision of prof. Sander Otte at the TU Delft. It contains measurements done with a scanning tunneling microscope (STM) on individual titanium atoms adsorbed on MgO thin films on top of Ag(100). Using electron spin resonance (ESR) methods, transitions between different spin states of a single atoms can be driven, revealing their magnetic state space. By using DC pulses in a pump-probe scheme, we inject a single spin excitation into the atomic structures and observe the resulting dynamics. This way, we are able to study the propagation of a spin excitation between the electron spins of individual magnetic atoms as well as between the electron spin and the nuclear spin within a single atom. The dataset is ordered by chapter that contains experimental data.

本数据集包含卢卡斯·M·维尔德曼（Lukas M. Veldman）在代尔夫特理工大学（TU Delft）桑德·奥特教授（prof. Sander Otte）指导下完成的博士论文《表面原子自旋的相干动力学》（Coherent dynamics of atomic spins on a surface）中，用于生成所有实验绘图的原始数据文件与分析代码。本数据集涵盖了在Ag(100)衬底上方的MgO薄膜表面吸附的单个钛原子的扫描隧道显微镜（scanning tunneling microscope, STM）测量结果。借助电子自旋共振（electron spin resonance, ESR）手段，可驱动单个原子不同自旋态间的跃迁，进而揭示其磁状态空间。通过泵浦-探测方案中的直流脉冲，我们向原子结构注入单个自旋激发并观测其引发的动力学过程。借此，我们能够研究单个磁性原子的电子自旋之间，以及单个原子内部电子自旋与核自旋之间的自旋激发传播行为。本数据集按照其对应实验数据所在的论文章节进行编排。
