“…In the case of oxide deposition, oxygen atoms can even be ejected from the film when the bombardment becomes stronger [9,10]. These extreme conditions of preparation lead to interesting reducing preparation conditions from which non-stoichiometric or out-of-equilibrium oxides can result [11,12].…”

Elaboration and characterization of Fe1–xO thin films sputter deposited from magnetite target

et al. 2007

Majority of the authors report elaboration of iron oxide thin films by reactive magnetron sputtering from an iron target with Ar-O 2 gas mixture. Instead of using the reactive sputtering of a metallic target we report here the preparation of Fe 1-x O thin films, directly sputtered from a magnetite target in a pure argon gas flow with a bias power applied. This oxide is generally obtained at very low partial oxygen pressure and high temperature. We showed that bias sputtering which can be controlled very easily can lead to reducing conditions during deposition of oxide thin film on simple glass substrates. The proportion of wustite was directly adjusted by modifying the power of the substrate polarization. Atomic force microscopy was used to observe these nanostructured layers. Mössbauer measurements and electrical properties versus bias polarization and annealing temperature are also reported.

“…Some of the performed studies aim to prepare magnetic composites by embedding magnetic particles in a non-metalic matrix [1][2][3][4][5][6]. Other authors deal with the incorporation of magnetic particles into a metallic non-ferromagnetic matrix [7][8][9][10][11] in order to modulate their magnetic properties. There are also studies focused in the preparation of magnetic composites with ferromagnetic matrix [12][13][14][15][16].…”

“…Different techniques have been used for magnetic composites preparation: milling methods [1,5,6,12,15], sol-gel [2,3], ion implantation [4], dc sputtering [8], RF-sputtering [9,10] or chemical synthesis [11,14]. Electroless [16] has been also tested in the preparation of hard-magnetic composites.…”

“…Copper-magnetite composites have been previously prepared by ball-milling copper oxide and iron under argon [6], by Fe(II) disproportionation in basic media and simultaneous Cu(II) reduction [19] or RFsputtering [20]. The aim of the current work is to produce copper-magnetite composites by working at low temperature and at normal pressure.…”

Electrodeposition of copper–magnetite magnetic composite films

2007

Electrodeposition was demonstrated to be useful for the preparation of copper-magnetite magnetic composites. An acidic bath was tested for the incorporation of nanometric magnetite (Fe 3 O 4 ) particles into an electrodeposited copper matrix. Cationic surfactant (dodecyltrimethylammonium chloride-DTAC) was used to keep particles suspended in the electrolyte as well as to assist magnetite incorporation. The influence of several parameters (bath temperature, deposition technique, stirring regimes and deposition conditions) on composites composition was analysed. Low stirring rate, moderate temperature (15°C) and an applied magnetic field provided a greater incorporation of magnetite. Field emission scanning electron microscopy revealed magnetite distribution through the deposit thickness. Electrodeposited composites showed ferromagnetic behaviour. Magnetic force microscopy showed a magnetic response for the composites.
