Tailoring Fe/Ag Superparamagnetic Composites by Multilayer Deposition

, 2005
The magnetic properties of Fe/Ag granular multilayers were examined by SQUID magnetization and Mossbauer spectroscopy measurements. Very thin (0.2 nm) discontinuous Fe layers show superparamagnetic properties that can be tailored by the thickness of both

Quantification of pedogenic particles masked by geogenic magnetic fraction

Scientific Reports, 2021
Pedogenic magnetic fraction in soils is attributed to fine-grained particles, i.e. superparamagnetic grains. In the case of a strongly magnetic geogenic fraction, pedogenic magnetic contribution is hard to detect.

Orientation of Demagnetized Bees [PDF]

, 1980
The orientation of honey bee dances is affected by the earth's magnetic field. Honey bees possess localized, well-oriented, stable and superparamagnetic domains of magnetite.

Superparamagnetic ultrathin films

Journal of Applied Physics, 1997
The finite-temperature magnetism of ultrathin films such as sesquilayer Fe/W(110) and submonolayer Fe/Cu(111) is investigated. Based on renormalizations of Onsager’s exact solution of the two-dimensional Ising model it is shown that superparamagnetism is a common phenomenon in imperfect ultrathin films.

Ferroferric oxide/polystyrene (Fe3O4/PS) superparamagnetic nanocomposite via facile in situ bulk radical polymerization

eXPRESS Polymer Letters, 2010
Organo-modified ferroferric oxide superparamagnetic nanoparticles, synthesized by the coprecipitation of superparamagnetic nanoparticles in presence of oleic acid (OA), were incorporated in polystyrene (PS) by the facile in situ bulk radical ...

The formation and ordering of local magnetic moments in Fe-Al alloys

, 2007
With density functional theory, studied are the local magnetic moments in Fe-Al alloys depending on concentration and Fe nearest environment. At zero temperature, the system can be in different states: ferromagnetic, antiferromagnetic and spin-spiral ...

Nanomaterials Based on Fe₃O₄ and Phthalocyanines Derived from Cashew Nut Shell Liquid

Molecules, 2019
In this work we report the synthesis of new hybrid nanomaterials in the core/shell/shell morphology, consisting of a magnetite core (Fe3O4) and two consecutive layers of oleic acid (OA) and phthalocyanine molecules, the latter derived from cashew nut ...
