“…In the literature on amorphous and nanocrystalline materials [18][19][20][21][22][23], there are many examples of alloys containing Zr and/or Y. Based on these and our own studies, it can be postulated that a higher Zr and/or Y content in the alloy causes a significant deterioration in the so-called soft magnetic properties; this can be observed as: reduction in saturation magnetization and magnetic permeability values and increase of the coercivity and core losses over a single magnetization-demagnetization cycle.…”
