Magnetite is both a common inorganic rock-forming mineral and a biogenic product formed
by a diversity of organisms. Magnetotactic bacteria produce intracellular magnetites of high …

In this paper, the unusual properties of amorphous soft magnetic wire with Fe-based or Co-
based in compositions have been discussed: giant magnetoimpedance effect (GMI), giant …

Nanocrystalline particles of cobalt ferrite (CoFe2O4) were prepared by a combustion wave
method, based on the Self-propagating High temperature Synthesis technique (SHS), using …

We present ferromagnetic resonance (FMR) experiments on two low-interacting
nanoparticle systems: Fe3O4 and CoFe2O4 corresponding to low-and high-anisotropy …

This study reports on the use of ferromagnetic resonance (FMR), at various microwave
frequencies (1.1 GHz, 3.5 GHz, 9.4 GHz, and 33.9 GHz), to investigate nanosized …

Nanomagnetism is both a fundamental and applied challenge. The magnetic properties
observable on a macroscopic scale are due to a very large number of atoms and, therefore …

Ferromagnetic resonance (FMR) experiments were performed as a function of temperature
(10–300K) on γ-Fe2O3 nanoparticles prepared by a sol–gel method. By measuring at …

We obtain magnetic properties of magnesioferrite nanoparticles grew in a magnesiowstite
crystalline matrix by analyzing the temperature dependence of the coercive field and the …

Nanocrystalline particles of magnesioferrite (MgFe2O4) were prepared by a sol-
gel/combustion method using iron nitrate, Fe (NO3) 3.9 H2O, magnesium nitrate, Mg (NO3) …

Ferromagnetic resonance (FMR) in exchange-coupled bilayer films has been the subject of
intensive studies in recent years. From the experimental viewpoint, a characteristic feature of …
