====== Magnetism@home ====== ===== Project Description ===== Magnetism@home is a research project that uses Internet-connected computers to explore the equlibrium, metastable and transient magnetization patterns (first and foremost in nano-scale magnetic elements and their arrays, but later other systems may be considered). To understand scientific side of things: * Please see [[http://arxiv.org/abs/1002.4199|this preprint]] (latest and the most complete in this series of works) and references therein. * In this project we evaluate numerically the total (exchange + magnetostatic) energy of these magnetization distributions (using finite elements and a special "thin film" variant of [[http://en.wikipedia.org/wiki/Fast_multipole_method|fast multipole method]]) with the aim to minimize this energy numerically to build maps of ground and metastable states in magnetic nano-elements of various shapes. * The source code is [[http://fti.dn.ua/cgi-bin/viewvc.cgi/nanomagnFMM/trunk/?root=main|here]]. * Currently the program demonstrated sufficient precision for building the map of ground states. Improving its precision for resolving the metastable states is in progress. ==== Author(s) ==== The project is based at Donetsk Institute for Physics and Technology. ==== Credentials ==== * Website: **http://www.fti.dn.ua/magnetism/** * Join to team: **[[http://www.fti.dn.ua/magnetism/team_display.php?teamid=66|Ukraine]]** ==== Significant dates ==== * First seen on: **2008-06-15** * Date of completion: Project Suspended ===== Features ===== ==== OSes & Applications ==== ^ ^ {{:uk:win.png|}} ^ {{:uk:linux.png|}} | ^circleFMM | {{:ru:yes.gif|}} | {{:ru:yes.gif|}} | ^circleFMMNC | {{:ru:yes.gif|}} | {{:ru:yes.gif|}} | ^circleFMMNC | {{:ru:yes.gif|}} | {{:ru:yes.gif|}} |
