Abstract
Soft amorphous Fe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">76</sub> Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">13</sub> B <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> microwires were fabricated by Taylor-Ulitovsky technique and an external Co <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">90</sub> Ni <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sub> shell with magnetically harder behavior was additionally grown by combined sputtering and electro-plating techniques. The effect of annealing treatment at temperatures up to 700 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C for 1 h on low-frequency coercivity and the ferromagnetic resonance, FMR, frequency for single and biphase microwires was investigated. The properties after low temperature annealing (up to 500 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C) are reasonably maintained, which indicates the suitability of these families of wires for sensing applications up to relatively high temperatures. Nevertheless, low and high frequency properties are significantly deteriorated after crystallization of the amorphous core. FMR behavior was analyzed by fitting to Kittel equation for annealed samples. The observed different absorption peaks are correlated with the presence of the soft core and the external shell.
