µMAG -- Micromagnetic Modeling Activity Group
As part of the NIST Center for Theoretical and Computational Materials Science
(CTCMS) mission to develop and apply state-of-the-art theoretical and
computational materials science techniques, the micromagnetic modeling
activity group (µMAG) was formed to address fundamental issues in
micromagnetic modeling. Micromagnetics deals with magnetic materials on a
mesoscopic scale which is larger than the atomic scale, yet small enough that
bulk material properties are an inadequate description of the material.
Micromagnetic calculations find application in both permanent and soft
magnetic materials, in magnetic recording media, and in magnetic devices such
as recording heads and magnetic field sensors.
Part of what µMAG does is to facilitate communication between
people working in micromagnetics and in related areas. We have
sponsored a number of workshops and reports are available. We also maintain a
mailing list for announcements
and for discussion of micromagnetics.
One of the two technical µMAG activities is to develop standard
problems that will allow researchers to compare computational
techniques, identify problems, and detect programming bugs.
The second technical µMAG activity arises from a demand for
easy-to-use software for doing computational micromagnetics. While
it may still be true that the reliability of the results depends
on the skills of the operator, several freely distributed
packages are available.
Membership in µMAG is open to anyone interested in micromagnetics.
