We review the structural, magnetic and transport properties of double perovskites (A 2 BB'O
6) with ferromagnetism above room temperature. Ferromagnetism in these compounds is …

Nanoparticulate materials are experiencing increasing attention mainly because of the
unique combination of small size, exotic properties and processability, opening the …

Fe 3 O 4 nanoparticles have been made by a co-precipitation method with an average size
of 13 nm. Raman measurements show that there is also a small fraction of maghemite that is …

We report the successful synthesis of ferrimagnetic magnetite powders made using an arc-
discharge method in a partial oxygen atmosphere. X-ray and electron diffraction …

Ferromagnetic order is observed in Gd ion implanted ZnO crystals after annealing at 650 C
in a vacuum and we find that it is intrinsic and extends to depths of up to 40 nm. The …

Spintronics, or spin-based electronics, is a rapidly growing multidisciplinary research area in
the development of physical mechanisms based on the spin as well as the charge of an …

We study the enhanced magnetic moment observed in epitaxial magnetite (Fe 3 O 4)
ultrathin films (t< 15 nm) grown on MgO (001) substrates by means of pulsed laser …

In this paper, we demonstrate that films of magnetite, Fe3O4, can be deposited by the
electrochemical reduction of a Fe (III)-triethanolamine complex in aqueous alkaline solution …

Polystyrene-coated Fe 3 O 4 nanoparticles through surface engineering exhibit an
intergranular tunneling magnetoresistance (MR) ratio of 22.8% at room temperature and a …

A “retrosynthetic analysis” for the synthesis of gold nanobowls is shown in Figure 1a. We
hypothesized that nanobowls 1 could be obtained from heterodimeric NPs (heterodimers; …
