Amorphous microwires have attracted growing interest in recent years due to their outstanding soft magnetic properties.The giant-magnetoimpedance (GMI) is the most attractive features derived from microwires thus enabling a number of applications, such as microwave sensors, magnetic detectors, etc.1 The significance of wire-composites have also grown due to their solid application interest in sensing and cloaking areas.2 We demonstrated in the present study the important roles of extemal tensile stress and a so-called combined current modulation annealing (CCMA) technique in influencing the GMI and microwave properties of microwires and their composites.
