Shaping the Assembly of Superparamagnetic Nanoparticles [PDF]

ACS Nano, 2019
Superparamagnetism exists only in nanocrystals, and to endow micro/macro-materials with superparamagnetism, superparamagnetic nanoparticles have to be assembled into complex materials. Most techniques currently used to produce such assemblies are inefficient in terms of time and material.

Superparamagnetism-induced mesoscopic electron focusing in topological insulators [PDF]

, 2016
Recently it has been shown that surface magnetic doping of topological insulators induces backscattering of Dirac states which are usually protected by time-reversal symmetry [Sessi et al., Nat. Commun. 5, 5349 (2014)].

Mechanochemical synthesis and magnetic properties of maghemite [PDF]

Vojnotehnički Glasnik, 2011
This work presents the results of an investigation on maghemite (γ -Fe2O3) nanoparticles magnetic properties, which show superparamagnetic behavior i.e. superparamagnetism. Nanoscale maghemite samples were obtained by the mechanochemical method.

Room-temperature superparamagnetism due to giant magnetic anisotropy in MoS defected single-layer MoS2 [PDF]

Journal of Physics: Condensed Matter, 2017
Room-temperature superparamagnetism due to a large magnetic anisotropy energy (MAE) of a single atom magnet has always been a prerequisite for nanoscale magnetic devices.
