DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NSCM/71/">Th
 e Landau-Lifshitz-Gilbert equation with Dzyaloshinki-Moriya interaction: n
 umerical aspects</a>\nby Michele Ruggeri (University of Strathclyde) as pa
 rt of Nečas Seminar on Continuum Mechanics\n\n\nAbstract\nThe talk will b
 e split into two parts.\nIn the first one\, we discuss the numerical appro
 ximation of the Landau-Lifshitz-Gilbert equation\n(LLG) for the case in wh
 ich the energy (and\, hence\, the effective field appearing in LLG) includ
 es\nthe Dzyaloshinki-Moriya interaction (DMI)\, the fundamental ingredient
  for the enucleation and stability\nof chiral magnetic skyrmions. In the s
 econd part\, we discuss a limiting model for micromagnetic thin\nfilms in 
 the presence of bulk DMI\, where we focus on the limiting behavior of the 
 magnetization\nas the thickness of the film goes to zero. We show that the
  reduced model unveils some physics\nand discuss its practical implication
 s for computations. The results presented in the talk have been\nobtained 
 together with Giovanni Di Fratta (University of Naples Federico II)\, Elis
 a Davoli\,\nCarl-Martin Pfeiler\, and Dirk Praetorius (TU Wien).\n
