A critical parameter in characterizing the properties of single-domain nanoparticles is their magnetic relaxation time. It must be known, for example, to estimate anisotropy from magnetization versus temperature measurements. The time it takes relax also determines behavior particles various oscillating applied fields, which critically important application particle imaging and hyperthermia treatment. However, an analytic expression this has been generally missing. Brown's [Phys. Rev. 130,...
The energy of a Néel skyrmion in magnetic film with interfacial DMI is developed analytically, the finite thickness taken into account. Many theories for skyrmions use models that are only accurate limit vanishes. One theory [Büttner et al. Sci. Rep. 8, 1 (2018)] provides exceptionally expressions films, but does not yield an analytic solution size, plus it contains contributions which found using fitting methods. Here, we approximate demagnetizing by examining form magnetostatic Green's...
