“…So far, studies on magnetic wood have mostly focused on ferrite particle modified wood, such as Fe 3 O 4 [14], CoFe 2 O 4 [15], MnFe 2 O 4 [16] and so on. Fe, Ni and their alloys are very important soft magnetic materials due to their higher saturation magnetization and smaller coercive forces when compared with ferrites [17,18,19,20]. Furthermore, they have a wide range of applications, such as acting as electromagnetic wave absorbers, transformers, magnetic sensors and magnetic recording heads [21,22].…”

Magnetic FeNi3 nanoparticles were synthesized in the internal structure of wood through an in situ fabrication approach. The morphology, crystalline phase and chemical composition of the FeNi3 modified wood was investigated by X-ray powder diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) with energy-dispersive X-ray (EDX) analysis and X-ray photoelectron spectroscopy (XPS). SEM confirmed that the magnetic nanoparticles were densely dispersed in the wood matrix. The magnetic hysteresis loops showed that the magnetism of composites is dependent on the amount of FeNi3 loading. The saturation magnetization of magnetic wood increases from 6.3 to 10.8 emu/g with an increase of FeNi3 loading from 12 to 18 wt %. Furthermore, magnetic wood showed significant directional dependence. The presented work will provide a feasible pathway for producing wood composite products.

To realize the application of Ni films in magnetic recording media, giant magnetoresistive sensors and microelectromechanical systems, it is necessary to control and improve the magnetic and electrical properties of the films. In this paper, Ni nanocrystalline films with different thicknesses and growth rates are prepared with or without a high magnetic field (HMF). The effects of a HMF on the growth, magnetic and electrical properties of the Ni films are studied. The results show that HMF changes the growth structure of the Ni films from disordered stacked grains to columnar growth along the direction of the HMF. The columnar growth becomes more prominent at a high growth rate and large film thickness. The HMF increases the grain size but decreases the surface roughness of the Ni films. Due to changes in the growth structure, grain size and film quality, the saturation magnetization of the Ni films increase markedly (by 89%), and the resistivity and coercivity significantly decrease (by 89 and 58%, respectively) by the HMF. The remanence ratio of the Ni films is controlled by the HMF. This study shows that a HMF effectively controls the growth and improves the magnetic and electrical properties of Ni films.
