BORIS is open source and free to use for academic research and educational purposes. Please download the latest version below.
We are always interested in new collaborations, particularly for modelling of experimental results. If you require new modelling capabilities not currently included, then also please get in touch.
If you are interested in BORIS for commercial use please contact us.
BORIS is open source and found on GitHub: https://github.com/SerbanL/Boris2
A support forum is available on Google Groups: BORIS Computational Spintronics
Standalone manual is available here (also included with installers): BORIS Manual
Download notes: CUDA versions are available in single precision or double precision. For double precision you need a GPU able to efficiently handle double precision computations, otherwise it is recommended you download the single precision version. Alternatively you can download BORIS Lite without CUDA computations. Note, the CUDA versions include both CPU and GPU computations.
