Abstract
The magnetic properties and electrical resistivity of amorphous and na nocrystalline FeZr sad FeZrB(Cu) alloys are compared in a wide range o f temperatures (4 to 1000 K). The addition of boron increases the Curi e temperature of the alloys and induces a broad minimum in resistivity vs temperatures. A first step of crystallization occurs around 700 K in all the alloys, giving rise to alpha-Fe crystallites of very small size. Small amounts of boron greatly influence the exchange interactio ns, enhancing the ferromagnetic character of these compounds.
