Enhanced nanocomposite susceptibility by field-alignment of superparamagnetic particles
Mathias Zambach, Miriam Varón, Thomas Veile +7
Nanocomposites comprised of insulated magnetic single-domain particles are promising candidates for high-frequency, eddy current free, soft magnetic materials, but tend to suffer f…
The effect of demagnetization on the susceptibility of single-domain particles and assemblies
Mathias Zambach, Miriam Varón, Mads R. Almind +4
According to the classical laws of magnetism, the shape of magnetically soft objects limits the effective susceptibility. For example, spherical soft magnets cannot display an effe…
Printable Nanocomposites with Superparamagnetic Maghemite (-FeO) Particles for Microinductor-core Applications
Mathias Zambach, Miriam Varón, Thomas Veile +8
We here present printable and castable magnetic nanocomposites containing superparamagnetic 113 nm -FeO particles in an insulating poly-vinyl alcohol polymer matri…
Dipolar Attraction of Superparamagnetic Nanoparticles
Frederik L. Durhuus, Marco Beleggia, Cathrine Frandsen
For superparamagnetic nanoparticles (SMNPs), it is often claimed that the rapid thermal fluctuations of their magnetic moments negates the magnetic dipolar attraction, hence preven…
