Spin dynamics in patterned magnetic nanostructures at different timescales<\/strong>\u00a0<\/strong><\/p>\n

FIS2010-20979-C02-02, MICINN, PI: O.Fesenko (coordinated with K.Guslienko, University of the Basque Country, Spain)<\/p>\n

The global objective of the coordinated project is the increase of knowledge in fundamental understanding of the magnetisation dynamics in patterned magnetic nanostructures. The magnetisation dynamics occur at different timescales ranging from femto-seconds up to years (thermal stability of recorded information). Although at different timescales different physical mechanisms can contribute, the timescales are intrinsically linked to one another and their understanding can be fulfilled only in the synergy of a multiscale approach with the aim to combine different timescales in one unique physical picture. This common goal defines the particular directions of the proposed research:<\/p>\n

\u00a0\u00a0\u00a0\u00a0 1) Long time magnetisation dynamics of the non-uniformly magnetised (vortex-state) dots near the critical fields on the hysteresis loop. Temperature dependence of the vortex nucleation and annihilation fields.<\/p>\n

\u00a0\u00a0\u00a0\u00a0 2) Spin-polarized current induced vortex magnetization dynamics in nanopillars and nanocontacts. Spin torque vortex nano-oscillators of high power in microwave frequency range.<\/p>\n

\u00a0\u00a0\u00a0\u00a0 3) Excitation and prpogation of spin waves in two dimensional arrays of coupled dots. Tunning the pass- and strop-bands of the spin waves by changing the dot array ground state by external field pulses.<\/p>\n

\u00a0\u00a0\u00a0\u00a0 4) Femtosecond spin dynamics: basic equations, simulations and application to the vortex core polarization reversal in submicron magnetic dots.<\/p>\n

\u00a0\u00a0\u00a0\u00a0 The research serves as a physical basis for numerous future technological applications in magnetic and spintronic devices operating on nanoscale.<\/p>\n

\u00a0\u00a0\u00a0\u00a0 The aim of this proposal is to build a strong multiscale theoretical and computational framework for research into ultrafast spin manipulation in nanostructured magnetic materials which will be developed alongside state of the art experimental programmes. The collaboration between advanced theory and modelling of realistic systems and novel, cutting edge experiments \u00a0will lead to a deeper understanding of the fundamental physics of spin ordered materials and will lead to the development of advanced computational tools for the design of a new generation of materials for applications in ultrafast devices. This is an important and difficult challenge, as it spans multiple timescales (from femtoseconds to nanoseconds) and it involves the creation of interfaces between electronic structure calculations, atomistic models and mesoscopic simulations. This includes the important task to relate the theoretical predictions to experimental studies in order to verify the physical basis of the models and advise experimental developments in a rapidly moving field. To achieve these aims we have assembled a multidisciplinary consortium of leading theoretical (University of York,\u00a0University of Konstantz,\u00a0University of Uppsala,\u00a0Material Science Institute of Madrid (CSIC), Budapest University of Technology)\u00a0and experimental groups (University of Nijmegen, BESSY Berlin, University of Oxford, Queen’s University of Belfast)\u00a0along with important potential industrial users of ultrafast magnetic technology (Seagate Technology\u00a0and NXP).\u00a0\u00a0<\/span><\/p>\n
