Atomistic Spin Simulations in your Browser
Powerful to Use
The semi-classical atomistic spin model is an important part of research in magnetism, placed inbetween quantum mechanics and the micromagnetic model.
It can be used to describe many interesting phenomena, with this research group focusing especially on solitons, such as skyrmions or hopfions.
This website aims to simplify the learning process for people being introduced to interacting spin systems and to make spin dynamics easy to grasp and use.
The Web App showcases many features of the open source spin simulation framework Spirit, while the desktop user interface provides a significantly larger set of features.
See the Tutorial section for an introduction to the controls.
Simulate physical processes in real-time, get an understanding of different interactions, such as exchange or dipolar, and the magnetic configurations they can induce. See the influence of temperature and spin-polarised currents on localised states.
The web interface provides a peek at what a modern spin simulation code can do.
Change interaction constants and system parameters on the fly to see how they interact and how results may differ depending on your system.

Skyrmions in 2D Layer
A system where skyrmions are stable in a 2D monolayer. Move them around with a magnetic field or spin current, excite them with finite temperature or see the influence of spin interaction parameters
Skyrmions on a racetrack
A monolayer nanostrip in which skyrmions can be moved with a spin polarised current
