The performance of microwave devices mainly depends on the properties of materials used
in the fabrication. Knowledge of material properties at microwave frequencies is a …

Studies of many complex systems have revealed new collective behaviours that emerge
through the mechanisms of self-organised critical fluctuations. Subject to the external and …

Superparamagnetism exists only in nanocrystals, and to endow micro/macro-materials with
superparamagnetism, superparamagnetic nanoparticles have to be assembled into complex …

Magnetic metamaterials such as artificial spin ice offer a route to tailor magnetic properties.
Such materials can be fabricated by lithographically defining arrays of nanoscale magnetic …

The impact of in-plane and perpendicular magnetic fields on the spatial arrangement of
superparamagnetic nanospheres is explored. We utilize nanosphere self-organization …

We demonstrate the presence of an emergent magnetic anisotropy in square lattices of
circular mesospins. An external field is used to saturate the magnetization along the [10] and …

Metallic disks engineered on the 100 nm scale have an internal magnetic texture which
varies from a fully magnetized state to a vortex state with zero moment. The interplay …

Two-dimensional lattices of dipolar-coupled thin film ferromagnetic nanodisks give rise to
emergent superferromagnetic (SFM) order when the spacing between dots becomes …

We numerically study a mesoscopic system consisting of magnetic nanorings in the
presence of thermal magnetization fluctuations. We find the formation of dipolar-field …

Superparamagnetism occurs only in nanocrystals. Superparamagnetic nanomaterials
(SPNs) need to be assembled into complex materials, so as to use in particular applications …
