This workshop focusses on the development and applicability of micromagnetic simulations to scattering data, in particular diffuse or small angle scattering data and reflectometry, collected on magnetic materials. In some cases, this requires testing and validating simulations against experimental data, and in other cases, developing best practice for measurement strategies and protocols. The measurement styles described above often probe similar lengthscales, but the problems and requirements are often very different. In this workshop, we will bring together these aspects to promote information exchange between experts in these areas.
The workshop is split into two independent parts – this, the first one, will focus on setting out the current state-of-the-art in terms of measuring the scattering function S(q) using the techniques noted above, and in terms of micromagnetic theory and how it is applied to small angle neutron scattering and reflectometry. This will include demonstrations of how these simulations can be done.
At the end of this workshop, attendees should be able to see if a particular approach will be helpful in resolving their particular scientific question if it involves nanometer to micrometer magnetic structures, and how to make sure they collect sufficient data.
The workshop will be held over two afternoons:
Day 1:
Workshop aims and scope of the general problem
Current methods of extracting data and getting S(q) – reflectometry
Current methods of extracting data and getting S(q) – small angle neutron scattering
Confirmed speakers: Andreas Michels (University of Luxembourg), Dirk Honecker (ISIS Neutron and Muon Source), Sebastian Muehlbauer (TU Munich)
Day 2:
Introduction to micromagnetic theory
Application of micromagnetic theory to simulating SANS and reflectometry, with demonstrations or simulations for typical cases described, along with assessments for current limitations.
Confirmed speakers: Dmitry Berkov (General Numerics), Sergei Erokhin (General Numerics) and Joseph Paddison (Oak Ridge National Laboratory)
The follow up workshop will be held over the 8th and 9th of April, and will be focused on how to improve the state-of-the-art.
Day 3: (Part 2 on April 8-9)
Introduction and demonstration of MM simulation software packages, including cross-checks.
Discussion panel with software package representatives about implementing calculations into packages, with opinions on feasibility, necessary approaches, and further details
Confirmed speakers: Artur Glavic (Paul Scherrer Institut), Jonathan Leliaert (Ghent University)
Day 4: (Part 2 on April 8-9)
Round-table discussion with the aim of setting out finite tasks along with a plan for development.
