***General Introduction***
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. 
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.

***Equipment***
All measurements were performed using a commercial low-temperature Unisoku 1300 STM system.
All radiofrequent signals were produced using a Rohde & Schwarz SMB100B RF generator.
The DC pulses were produced using both an Agilent 81110A pulse generator and a Keysight M8195a arbitrary waveform generator (details for each individual measurement are described in detail in the thesis) .

***Description of the data in this data set***
The data included in this data set has been organised per chapter:
Chapter 3:  Experimental techniques 
Chapter 4:	Free coherent evolution of a two atom system 
Chapter 5:	Coherent single magnon dynamics at the atomic scale
Chapter 6:	Groundstate determination through hyperfine anisotropy 
Chapter 7:	Coherent electron-nucleus spin dynamics in a single atom
Within each folder the raw data files are grouped per measurement that is displayed as a figure in the chapter.
The code that was written to analyze, fit and plot the data is included.
Simply running the script will produce the corresponding figure from the raw data.
Most scripts are written in python, except for chapter 6, where we used Matlab.
