The magnetic properties bulk nanograin composite Nd-Fe-B/Fe-Co magnets is enhanced reducing the size and improving the distribution of the soft phase throughout the magnet. This was achieved through various coating technologies applied to coat melt-spun micrometer-sized Nd-Fe-B powder particles with thin alpha-Fe or Fe-Co layers. These coating techniques include sputtering, pulsed laser deposition,...
The authors studied the influence of microstructure and grain size, as well as Curie temperature, on the low-temperature aged Sm(Co0.45Cu0.4Fe0.15)5 alloy in relation to enhanced coercivity. Melt-spinning has been employed in order to achieved a wide range of grain sizes from micro- to nanometer level. XRD and TEM analysis were used to study the structure of as-spun ribbons and SQUID magnetometer...
In this study, Nd2Fe14B thin films with perpendicular anisotropy at the thickness as thin as 5 nm have been successfully prepared. The suitability of the films as perpendicular magnetic recording media has been discussed. The films were characterized by X-ray diffractometry (XRD), vibrating sample magnetometer (VSM) with maximum applied field 24 kOe, and scanning electron microscopy (SEM). The chemical...
In this paper, the potential for new device materials and insight into the effects of some of the different iron oxide forms on exchange bias with NiFe (Permalloy) was discussed. The iron-oxides have significantly different magnetic properties. Thin film bilayers were deposited using a dual ion-beam deposition technique that produced an antiferromagnetic iron-oxide layer composition that ranged from...
Ordered LiFeO2 powders were prepared by the sol-gel method. The crystal structures were measured by X-ray diffraction (XRD). Thermal analysis such as thermogravimetry analysis (TGA) and differential thermal analysis (DTA) were performed on the dried powder obtained from the LiFeO2 precursor solution. The particle morphology of the samples was observed using a scanning electron microscope (SEM). Magnetic...
We investigated the dependence of magnetic properties with composition in nanocrystalline Mn-Zn ferrites. Ferrite crystals were synthesized by a modified coprecipitation route where nucleation and crystal growth conditions were controlled during the reaction of 0.011M Fe(III) and 0.055M[Zn(II) + Mn(II)] solutions under alkaline conditions. When doping, suitable amounts of Gd(III) or Eu(III) salts...
