Abstract

Results on the analysis of the magnetoelastic and magnetostatic contributions in the total free energy of nearly zero magnetostrictive amorphous glass-coated nanowires prepared by means of rapid solidification are reported. The comparative study shows that both terms have values of the same order. However, the magnetostatic term is the most important one over a wide range of dimensions, being responsible for the domain structure formation and for the overall magnetic behavior of the investigated nanowires, which mainly consists in the appearance of an axial magnetic bistability. Even in the thinnest samples, the magnetostatic contribution is essential, in spite of an important magnetoelastic one, too. Calculated results agree with the experimental hysteresis loop data. The results are a key for understanding and controlling the magnetization processes in these novel nanowires.
