Abstract

Trilayers of Sm-Co/Mo/Fe were deposited by DC and RF magnetron sputtering on Si (100) substrate at 650 °C. Effect of very thin Mo interlayers on energy product of magnetic layers was studied. All the samples showed strong exchange coupling and single phase behavior. With increasing Mo interlayer thickness, we observed oscillating behavior of saturation magnetization and energy product. The rise in energy product was observed as 22% for 0.3 nm Mo interlayer as compared to sample without Mo interlayer.

However, the low temperature studies of these systems are a potential way to explore the actual exchange mechanism as well as the temperature dependence of the hard-phase anisotropy effect on the hard-soft coupling [19]. The type of substrate, under layer as well as incorporation of inter layer have predominant effect in deciding the magnetic properties of a magnetic material grown and hence several studies have been conducted in this respect [20–22]. The orientation of hard layer anisotropy (direction of easy axis) is affected by the type of the under layer (buffer layer) used.
SmCo₅/Co exchange-coupled films with high saturation magnetization, and hence high energy product were fabricated on MgO substrates by sequential deposition of elemental Sm and Co layers at 450 °C followed by subsequent annealing at the same temperature for 1 h. Formation of defects induced multi-layered structures and the composition of individual layers were confirmed through high resolution Scanning Transmission Electron Microscopy (HRSTEM) imaging acquired on high angle annular dark field (HAADF) detector and Energy Dispersive X-ray (EDX) spectroscopy. Micromagnetic simulations and magnetic measurements further confirmed that the observed structure is coupled in rigid phase between soft and hard magnetic layers and the enhancement in coercivity results due to the domain wall pinning at the defects sites. This leads to the magnetic energy density in the film of the order of 22.2 MGOe which is close to the bulk value and have potential applications towards Micro-Electro-Mechanical Systems.

We investigated the structural and magnetic properties of Sm(Co_0.7Fe_0.1Ni_0.12Zr_0.04B_0.04)_7.5 melt spun ribbons. Samples were arc melted then melt spun at 37 m/s up to 55 m/s to obtain ribbon for powdering. Annealing was performed in argon atmosphere for 30–75 min at 600–870°C. In as-spun ribbons the hexagonal SmCo₇ (TbCu₇-type of structure) of crystal structure was determined from x-ray diffraction patterns, while fcc-Co has been identified as a secondary phase. After annealing, the 1:7 phase of the as-spun ribbons transformed into 2:17 and 1:5 phases. X-ray patterns for as-milled powders exhibited very broad peaks making it difficult to identify a precise structure but represented the 1:7 structure after annealing at low temperature (650°C). TEM analysis showed a homogeneous nanocrystalline microstructure with average grain size of 30–80 nm. Coercivity values of 15–27 kOe were obtained from hysteresis loops traced up to a field of 5 T. The coercivity decreased as temperature increases, but it maintained values higher than 5 kOe at 380°C. The maximum energy product at room temperature increased, as high as 7.2 MGOe, for melt-spun isotropic ribbons produced at higher wheel speeds. Anisotropic ribbons had a maximum energy product close to 12 MGOe.
Effect of film thickness on magnetic properties of Cr/SmCo/Cr films
2012, Journal of Rare Earths
Cr/SmCo/Cr films with different SmCo thickness were deposited on glass substrates by magnetron sputtering, followed by an annealing process at 550 °C for 20 min. Experimental results showed that the SmCo film of 30 nm exhibited two-phase behavior in the demagnetization process, the obvious kink was observed near zero. For the SmCo film of 50 nm, the kink was invisible, and a single phase like behavior was obtained in the demagnetization process. The reversal behavior became consistent in the thicker films. Moreover, the coercivity reduced and the saturated magnetization increased obviously with the increasing thickness. X-ray diffraction results indicated that the average grain size of SmCo₅ in the thicker films were almost 30 nm, but the quantity of SmCo₅ grains increased with the increasing thickness, which enhanced the intergrain exchange coupling (IEC) of the SmCo₅ hard phases. The increase of IEC improved the magnetic properties of SmCo films with increasing thickness.
Effect of processing method on the microstructure of Nd <inf>4.5</inf>Fe<inf>77</inf>B<inf>18.5</inf> magnetic alloy
2012, Procedia Engineering
The effects of processing method including arc-melted process, rapid solidification and laser crystallization on the microstructure of Nd4.5Fe77B18.5 alloy were investigated. The results showed that the microstructure of the arc-melted alloy was composed of Nd2Fe14B, Fe3B and α-Fe. The microstructure for the melt-spun alloy at the surface velocity of the wheel of 3m/s was similar to that of arc-melted one. However, the constituent phases were composed of Nd2Fe14B and Fe3B, and the α-Fe was suppressed for the melt-spun alloy at the surface velocity of the wheel of 5m/s. At the surface velocity of the wheel of 7m/s and 10m/s, the microstructures were composed of Fe3B and amorphous. Increasing cooling rate, the grain size decreased from micron to nanometer. The completely amorphous microstructure was obtained at the surface velocity of the wheel of 20m/s. The uniform Nd2Fe14B/Fe3B nanocomposites were obtained during the amorphous melt-spun crystallization by laser crystallization process. After laser crystallization at 400mm/min, the mean grain sizes of Nd2Fe14B and Fe3B reached 30nm and 20nm, respectively.
