We report on tailoring of magnetic properties and GMI of Fe69B12Si14C5 glass-coated microwires by stress annealing. The induced magnetic anisotropy field depend on temperature and time of annealing and applied stress. At certain conditions considerable GMI effect (up to 65%) has been achieved. Application of the tensile stress drastically affects the shape of the hysteresis loop of stress-annealed sample and its GMI effect. In this way the shape of the hysteresis loop and GMI effect can by tailored by controllable way. (c) 2006 Elsevier B.V. All rights reserved.
