Journal of Science: Advanced Materials and Devices, 2016 We report an enhancement of low-field, high-frequency magneto-impedance (MI) response and circumferential domain structures of melt-extracted amorphous Co69.25Fe4.25Si13B13.5 microwires by dc Joule annealing. The current amplitudes of 5 mA, 10 mA, and 20

Low temperature magnetic behaviour of glass-covered magnetic microwires with gradient nanocrystalline microstructure [PDF]
, 2014 Slow nanocrystallization driving dynamics can be affected by the combination of two factors: sample residual stresses and sample geometry. This effect is evidenced at the initial stages of nanocrystallization of amorphous CoFeSiBCuNb magnetic microwires.

Local magnetization profile and geometry magnetization effects in microwires as determined by magneto-optical Kerr effect [PDF]
, 2013 The local magnetization profile along the length in magnetostrictive Fe-based magnetic microwires has been determined by magneto-optical Kerr effect. The study has been performed in microwires with different geometrical dimensions (i.e., diameter and ...

Magnetic Models of Cast Amorphous Microwires
Surface Engineering and Applied Electrochemistry, 2011 A theory of a magnetic domain model for glass coated amorphous microwires is studied. The obtained theoretical results are confirmed by experiments. Cast glass coated amorphous microwires with positive magnetostriction have a rectangle hysteresis loop, which is characterized by a coercive force stable magnitude.
