Quantum Magnetism Analysis Model
written by
Larry Engelhardt, Chad Garland, Cameron Rainey, and Austin Freeman
The Quantum Magnetism Analysis Model was created to help students as well as researchers who are studying magnetism. It provides a very simple interface for defining (theoretical) quantum spin models; sliders are automatically created to vary the parameters in the models; and several plots are automatically created to visualize the results. Within the program, several measured (experimental) data sets are included for a variety of real molecules. These provide the opportunity to experience the modeling process by varying the parameters in the model and exploring how the simulated results compare to the measured data.
The interactions between neighboring quantum magnetic moments ("spins") are modeled using the Heisenberg model; calculations are carried out by numerically diagonalizing the matrix representation of the Heisenberg Hamiltonian; and plots display the energy spectrum, magnetization, and magnetic susceptibility as a function of temperature and magnetic field. This simulation is a "Fully Integrated Tool for Magnetic Analysis in Research & Teaching," so we also refer to it with the acronym "FIT-MART". FIT-MART was developed using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking ejs_fitmart.jar file will run the package if Java is installed. In future versions of this simulation, curricular materials will be included to help students to learn about magnetism, and automated fitting routines will be included to help researchers quickly and easily model experimental data. FIT-MART was developed using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive.

Research With Spin Systems
Author: MuckrakerW M Building a spin system with fit-mart is based on crystalline structures already researched. Most of the papers for reference or study cost at least $35.00. The only other option is to find crystalline compounds created in nature which could be analogous to your own spin chain or cluster. I do believe the Internet will have information about such compounds because I have knowledge of both inorganic and organic chemistry. But without these papers as reference you're working somewhat in the blind.

Spin Systems - Multiparticle
Author: MuckrakerW M I found this simulator just what I needed to better understand spin-1/2, spin-0 and spin-1 particles. Since photons theoretically have zero mass the X parameters/fields in Tesla are usually set to zero. I'm not sure if the Lande g factor or gyromagnetic ratio g or the Bohr magneton apply to photons, bosons, since they carry no charge. Anyway I set these parameters to zero as well.
