The domain wall dynamics during magnetization reversal process of glass-coated amorphous Fe77.5Si7.5B15 bistable microwire was considered. Its domain structure deriving from the magnetoelastic and shape anisotropies consists of an axial single domain and two closure domain structures at the ends, plus an outer radial-helical shell in its surface. This articles report the measured domain wall velocities,...
Summary form only given. This paper focuses on the possibility of direct casting miniature NdFeB-based bulk permanent magnets in different three-dimensional shapes for various applications, with amorphous structure followed by subsequent optimal annealing. Nd3Dy1Fe66Co10B20 bulk nanocomposite permanent magnets in form of rods with diameters ranging from 0.5 to 0.8 mm have been prepared by devitrification...
In this paper, the authors have reported a new directional coupler for the cellular phones with an operating frequency of 0.8-2 GHz, which consisted of a coupled microstrip structure with an amorphous CoFeB magnetic thin film and a polyimide dielectric film.
FeCuNbSiB amorphous microwires with average diameter about 40 mum were fabricated by a specially designed melted quench facility. Anneal treatment at T=673K for 1 hour had been carried out for amorphous wires to obtain nanocrystalline grains with average grain diameter of 34 nm. Then, the heat treated microwires were cut into short fibers, the length and diameter ratio was about 2. The composite samples...
A cantilevered actuator is fabricated in this study by sputter deposition using amorphous Fe72Si14B14 as the magnetostrictive material. The displacement of the cantilever is observed with applying the magnetic field of 10 kA/m to the width direction of the cantilever. Results show that the displacement of the cantilever increased with decreasing substrate thickness, and has a peak value at the thickness...
