Nanoscale Ordering of Magnetosomes Under the Influence of a Magnetic Field Investigated by Small‐Angle X‐Ray Scattering

Small Structures, Volume 7, Issue 6, June 2026.
Recently, the synthetic Rhodospirillum rubrum ‘magneticum’ has been shown to enable the light‐driven production of magnetosomes (MAGs) in high yields. These membrane‐enveloped magnetic nanoparticles represent promising alternatives to their chemically synthesized analogs for many applications in the biotechnological and biomedical field.

Nanoscale Analysis of Superparamagnetic Systems

Acta Physica Polonica A, 2017
The paper refers to a kind of nanoscale characterization of superparamagnetic materials above and below the so-called blocking temperature. It is propose to apply the Stoner–Wohlfarth model of nanoparticles magnetization supplemented by the two-level kinetic model, determining behavior in T > 0.

Superparamagnetism-induced mesoscopic electron focusing in topological insulators

, 2021
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, Nat. Commun. 5, 5349 (2014)10.1038/ncomms6349].

Magnetoliposomes containing magnesium ferrite nanoparticles as nanocarriers for the model drug curcumin [PDF]

Royal Society Open Science, 2018
Magnesium ferrite nanoparticles, with diameters around 25 nm, were synthesized by coprecipitation method. The magnetic properties indicate a superparamagnetic behaviour, with a maximum magnetization of 16.2 emu g−1, a coercive field of 22.1 Oe and a ...

DC‐magnetometry Analytical Tool Driven by Spin Ordering Phenomena for Sensing Chemical Interactions at the Surface of Nanomaterials

Advanced Science, Volume 13, Issue 30, 28 May 2026.
The adsorption of AsV on akaganeite nanorods was found to provide a magnetic signature. A change in the surface spin order gave rise to a second peak in the zero‐field cooled curve. AsIII adsorption does not provide any change in the magnetic behavior of the sorbent.

Coincidence of superparamagnetism and perfect quantization in the quantum anomalous Hall state [PDF]

, 2015
Topological insulators doped with transition metals have recently been found to host a strong ferromagnetic state with perpendicular to plane anisotropy as well as support a quantum Hall state with edge channel transport, even in the absence of an ...
