Cactus-shaped core double-shelled FeCo/C/Fe<sub>2.5</sub>Cr<sub>0.5</sub>Se<sub>4</sub> nanostructures with a spiky surface were prepared by combining an arc-discharge process high-temperature solution chemical method.
Abstract Biodegradable implants help avoid the adverse residual effects and need for secondary surgeries associated with permanent implants. Recently, biodegradable metals (BMs), which are designed to gradually corrode within body, have gained significant research interest as promising materials meet this need. Iron (Fe) alloys fabrication implants, possess excellent mechanical properties. However, their corrosion rates can be too slow in physiological environments specific applications,...
A comprehensive review is given of recent advances in the study metastable phases rare-earth permanent magnets. The relations between structures and equilibrium transformations from former to latter are discussed. formation found depend on difference symmetries phases. magnetic properties metastable-phase magnets synthesized by various processes, such as mechanical alloying, milling, rapid quenching, hydrogenation, disproportionation, desorption recombination, solid-state reaction, solid-gas...
The magnetic properties of 10 nm size Ni(OH)2 nanoparticles prepared by sol-gel method have been studied. moments increase with decreasing temperature in a low applied field, which is due to the spin-frozen-like state at temperatures, and metamagnetic transition not clearly observed even an field 70 kOe effect. Furthermore, from paramagnetic antiferromagnetic occurs lower (22 K).
Exchange coupling has been realized in textured Nd2Fe14B/α-Fe multilayer films. A Mo spacer layer proved to be effective for preventing interdiffusion at the interface region between hard-magnetic Nd16Fe71B13 and soft-magnetic α-Fe these Anisotropic behavior of exchange films is observed by means magnetic measurements. Furthermore, critical correlation length found exhibit anisotropic behavior, which smaller parallel than perpendicular direction same temperature. This can well explained...
The permittivity and permeability of Zn or Zn(Fe) nanoparticles with core-shell structure were investigated for frequencies from 2 to 18 GHz. particles contain oxides shell in the form ZnO, while core material is Zn(Fe). resonance frequency corresponds maximum microwave absorption Zn/ZnO nanocapsules, which not shifted changing thickness absorbent. However, doping Fe (about 40%) position lower increasing
The permittivity and permeability of the Tb-doped undoped Fe core-shell nanoparticles were investigated for frequencies from 2 to 18 GHz. particles synthesized by arc discharge contain some oxygen, probably in form Fe2O3, Fe3O4, Tb2O3, whereas core material is Fe. Both electromagnetic materials constants morphology are changed Tb addition, which gives rise shifts higher thinner thicknesses maximum microwave absorption nanoparticles.
