2nd Advanced VAMPIRE Workshop

22nd - 26th July 2019

2nd Advanced VAMPIRE Workshop

The second advanced VAMPIRE workshop will be held in the Department of Physics at the University of York, UK between 22nd - 26th July 2019. The workshop is targetted at scientists and engineers wishing to study magnetic materials and devices at the atomistic level. The workshop will cover the basic and advanced features of the VAMPIRE code which can be used to study a wide range of magnetic materials and phenomena, from zero temperature ground states, equilibrium properties and magnetization dynamics.

The workshop will be a mixture of lectures, demonstrations and practical sessions giving hands-on experience of atomistic modelling of magnetic materials with Monte Carlo and Atomistic Spin Dynamics methods. On the last day there will be a project specific activity where researchers can get help for simulating systems and properties for their specific interests. Finally there will be an opportunity to discuss the future direction of the VAMPIRE code and new features to be developed which can best serve the magnetism and spintronics commmunities.

Programme

The workshop will cover the main features of the VAMPIRE code including the latest algorithmic developments and methods. In particular we will introduce the parallel capabilities of the code and how to use high performance computing resources such as ARCHER to simulate large scale systems and devices.

1st Advanced VAMPIRE Workshop

The first advanced VAMPIRE workshop will be held in the Department of Physics at the University of York, UK between 10th - 15th September 2017. The workshop is targetted at scientists and engineers wishing to study magnetic materials and devices at the atomistic level. The workshop will cover the basic and advanced features of the VAMPIRE code which can be used to study a wide range of magnetic materials and phenomena, from zero temperature ground states, equilibrium properties and magnetization dynamics.

The workshop will be a mixture of lectures, demonstrations and practical sessions giving hands-on experience of atomistic modelling of magnetic materials with Monte Carlo and Atomistic Spin Dynamics methods. In addition new developments in the capabilities of atomistic models will be presented by a small selection of speakers to give a flavour of the exciting developments in this area. Finally there will be an opportunity to discuss the future direction of the VAMPIRE code and new features to be developed which can best serve the magnetism and spintronics commmunities.
