Vampire: a software package for atomistic simulations of magnetic materials

Vampire is an open source software simulation package for atomistic simulation of magnetic materials developed at the University of York. The objective of vampire is to provide a community standard tool for atomistic simulation of magnetic materials with high performance and an easy-to-use interface.

Using a variety of common simulation methods it can calculate the equilibrium and dynamic magnetic properties of a wide variety of magnetic materials and phenomena, including ferro, ferri and antiferromagnets, core-shell nanoparticles, ultrafast spin dynamics, magnetic recording media, heat assisted magnetic recording, exchange bias, magnetic multilayer films and complete devices.

Getting vampire

Vampire is available in binary form from the offical website at, or the source code is available from github. The code runs in serial and parallel on Windows, OS X and linux. The offical website now includes a comprehensive overview of the software features, as well as a manual, tutorials and example input files.


Vampire is designed to be highly flexible to deal with a wide variety of problems using a diverse set of simulation tools and methods. The capabilities of the code can be summarised broadly in terms of the simulation methods, standard problems, structural properties and features of the code, all of which can be combined to tackle almost any problem.

Using vampire

Vampire is open source software under the GPLv2 Licence and free to use for both commercial and academic research. I would ask that if you use the software please let me know as it is most helpful to know how many people/organisations are using it for their research. When citing the software please link to the vampire homepage at and cite the review article of the methods implemented in vampire, Atomistic spin model simulations of magnetic nanomaterials, R F L Evans, W J Fan, P Chureemart, T A Ostler, M O A Ellis and R W Chantrell, J.
