Query: Frequency-dependent magnetic susceptibility of magnetic nanoparticles in
  a polymer solution: a simulation study   Magnetic composite materials i.e. elastomers, polymer gels, or polymer
solutions with embedded magnetic nanoparticles are useful for many technical
and bio-medical applications. However, the microscopic details of the coupling
mechanisms between the magnetic properties of the particles and the mechanical
properties of the (visco)elastic polymer matrix remain unresolved. Here we
study the response of a single-domain spherical magnetic nanoparticle that is
suspended in a polymer solution to alternating magnetic fields. As interactions
we consider only excluded volume interactions with the polymers and
hydrodynamic interactions mediated through the solvent. The AC susceptibility
spectra are calculated using a linear response Green-Kubo approach, and the
influences of changing polymer concentration and polymer length are
investigated. Our data is compared to recent measurements of the AC
susceptibility for a typical magnetic composite system [Roeben et al., Colloid
and Polymer Science, 2014, 2013--2023], and demonstrates the importance of
hydrodynamic coupling in such systems.
