Magnetometry Data Analysis and Visualisation Program (QuantumDesign .dat file analyser)

Developer: Dr. Conrad Gillard

This program automates the following tasks:

1. This program performs the following analysis on Quantum Design .dat files:
   
   • Converts the moment data into units specified by the user, or to susceptibility.
     
   • Identifies datasets corresponding to M vs T experiments and performs Curie-Weiss analysis, based on linear fitting ranges specified by the user
   • Repeats this analysis with the modified Curie-Weiss law, enabling users to compare the two sets of results
   • Optionally uses a median filter to remove outliers from the fitting calculations
   • Identifies datasets corresponding to M vs H experiments, which will subsequently be plotted
   • Removes a linear component to account for diamagnetic contributions, enabling users to compare the two sets of results
2. The program then generates the following outputs:
   
   • A folder containing CSVs of each experimental dataset, that may be used for any subsequent calculations
   • A folder containing Python plots of each experimental dataset, and the linear fits used in Curie Weiss analysis
   • A folder containing Origin graphs of the above data, exported as .png files
   • An Origin project containing the above graphs
   • A Word document containing the Origin graphs, and tables of the calculated Curie-Weiss parameters
   • A PowerPoint presentation containing the Origin graphs.

This program is in the following format:

• A Python program, which is operated via an Excel interface.
• We have developed this program architecture in order to enable usage of the program without knowledge of coding.
• All elements of the program are packaged in an installer application.
• Consequently, installation is as simple as double clicking the installer icon, and selecting your preferred options in the Wizard that will appear.
• The installation process and the benefits of this architecture are demonstrated in the Program Installation and Architecture Video.

This program has the following system requirements:

• Origin 2021 or later.
• Microsoft Excel (not Libre Office or other equivalents).

Instructions to use this program are found:

• In the Manual and QuickStart Guide that are included with the program
• In the form of the Program Demonstration Video.

The following additional files are included with this download:

• Two example data files on which to test the program.
• Origin, Word and PowerPoint templates that determine the appearance of the outputs, and may be modified by the user.
• A Python distribution, to ensure that the program works immediately after running the installer, and no setup is required by users.
