This repository provides a "library" for Monte Carlo simulations of dipolar spin ice and related pyrochlore systems and computing thermal averages of quantities like magnetisation, emergent monopole density, and structure factors. It also includes one program file, sweep.cc, which computes magnetisation and monopole density in continuous field sweeps for spin ice with local [111] fields. The latter was used to generate all simulation results shown in the paper Monopole density and antiferromagnetic domain control in spin-ice iridates.
After installing the dependencies, the executable sweep.out can be compiled and linked using the command
make sweep.out
in the directory code. The simulation results presented in the paper can then be reproduced using the commands
./simulate.sh
./postprocess.sh
The latter averages the raw simulation data into 0.01 tesla bins to smoothen the curves.
Other simulation executables for other spin-ice-related projects can readily be assembled using the simulation modules available in the directory code/spinice
